On January 31st, 2024, JAC Ruifeng RF8 was officially launched, becoming the third vehicle equipped with a large cylindrical battery. The other two are: JAC Yttrium 3, which was listed on June 16, 2023, and Tesla Cybertruck, which recently toured China.Down-to-earth right 钠片 In-depth research is the only way to pursue development. https://www.canrud.com/products/detail/3bf1b87d8f134de9a7bbdefb08cf432a

　　Of course, the official name of Cybertruck in China is Cybercross Country Wagon.

　　Source/New Energy Prospective Shooting

　　On January 28, 2023, the much-watched Tesla Cybercross-country wagon officially opened its domestic tour. The eight cities are Shanghai, Beijing, Hangzhou, Xi ‘an, Shenzhen, Chongqing, Chengdu and Nanjing.

　　Musk has previously said that the 4680 battery will be an important part of Tesla’s 2023 plan. All future electric vehicles of Tesla, including Model Y, Semi semi-trailer truck, Cyber electric truck and Roadster 2 electric sports car, will use 4680 large cylindrical batteries.

　　According to Musk’s vision, the large cylindrical battery can increase the cruising range of Tesla electric vehicles by 16% and reduce the production cost by 50%, which is even considered as “the light of lithium battery”.

　　But in fact, after Musk launched 4,680 large cylindrical batteries in 2020, it was not until mid-2023 that large cylindrical batteries began to be mass-produced on a small scale. According to public information, in June 2023, Tesla produced the 10 millionth battery cell, and by October 2023, the 20 millionth 4680 battery cell was born. This means that the annual output of large cylindrical battery cells is 30 million, which is equivalent to the battery consumption of 24,000 Cybertruck.

　　Obviously, such battery production is out of proportion to the order volume of Cybertruck with more than 2 million units.

　　On the other hand, Tesla previously claimed that the negative electrode of the 4680 battery would be made of silicon carbide to improve the energy density. However, after disassembling the battery, a technical organization found that its negative electrode did not contain silicon carbide, but graphite. Some media said that the energy density of 4680 large cylindrical battery is not as good as that of 2170 small cylindrical battery.

　　In this way, the large cylindrical battery is still far from the “light of lithium battery”.

　　01

　　What exactly is a large cylindrical battery?

　　At present, the power batteries of new energy vehicles can be divided into three types according to their shapes: square, soft bag and cylinder. Square is the mainstream form, accounting for about 60% of the market share.

　　Cylindrical batteries can be divided into two types: small cylindrical batteries and large cylindrical batteries. The former is a “2170 cylindrical battery” with a diameter of 21 mm and a height of 70 mm, which is a mature product. The large cylindrical battery is a battery with a diameter of 46 mm and a height of 80 mm, which is also often called “4680 cylindrical battery”.

　　In Tesla’s view, a cylindrical battery with a diameter of 46mm is the best size for battery life improvement and cost reduction. As the diameter becomes smaller, the number of battery sections required by the whole vehicle will increase, and the management of BMS (Battery Management System) will become more difficult. However, as the diameter increases, the number of battery sections decreases, but the heat dissipation of the battery core becomes a difficulty.

　　There is no “critical point” in height, so there are 4680, 4695 and even 46120 batteries.

　　In terms of endurance, the upper limit of energy density of large cylindrical battery is higher, and it has higher safety. Take Jianghuai Ruifeng RF8 as an example, its lithium iron phosphate battery has an energy density of 180Wh/kg, while the general Ferrous lithium phosphate density is 100-150Wh/kg. Under the premise of the same weight, the large cylindrical battery can provide a longer cruising range and higher performance for electric vehicles.

　　An important reason for Musk to launch a large cylindrical battery is its low cost.

　　For Musk, carrying a larger 4680 battery can reduce the number of battery cells and welding accessories, thus simplifying the battery pack structure and reducing the use of materials. In addition, the cathode material of Tesla 4680 battery is made of Nickel Cobalt Aluminum (NCA), which is relatively cheap and can provide higher energy density.

　　”The rise of large cylindrical batteries is related to the market strategy of car companies to reduce costs and increase efficiency.” Some people in the industry have a forward-looking analysis of new energy sources. Because of the characteristics of reduced structure of the whole package, large cylindrical batteries have certain advantages in overall cost, as well as high energy density and good power performance.

　　02

　　Battery manufacturers compete for layout

　　Therefore, many battery manufacturers have chosen to follow the pace of Tesla.

　　In September 2020, Tesla CEO elon musk announced that Tesla would produce 4680 batteries. “For the 4680 battery, we still have a lot of work to do. Although it looks like a battery with a diameter of 46 mm and a height of 80 mm, it itself contains amazing new technologies. ” Musk said.

　　Subsequently, Panasonic, LG, Yiwei Lithium Energy, Yuanjing Power, Contemporary Amperex Technology Co., Limited, BIC Battery and other enterprises successively announced that large cylindrical batteries would be included in the company’s technological development path.

　　In September 2023, Yiwei Lithium Energy said on the investor interaction platform that the company’s first large cylindrical production line was completed by the end of 2022. In the first half of 2023, the millionth battery was rolled off the assembly line.

　　Source/Yiwei Lithium Energy official website New energy forward-looking screenshot

　　In May 2023, a wholly-owned subsidiary of Yiwei Lithium Energy signed a land purchase agreement with a Hungarian land seller to purchase its land in the northwest industrial zone of Debrecen for the production of cylindrical power batteries; In June of the same year, the 46 series large cylindrical light battery pack was first released; Yiwei Lithium Energy even said that the 46 series power energy storage batteries have achieved the intentional demand of customers in the next five years, totaling about 392GWh; The production capacity of large cylindrical batteries has been planned to exceed 100GWh, and mass production is expected to be realized in 2023-2024.

　　Panasonic’s chief technology officer in charge of electric vehicle batteries recently said that Tesla may provide cheaper electric vehicles to the market in the near future because Panasonic will launch the improved new generation of 2170 batteries and 4680 batteries as early as 2024.

　　According to the incomplete statistics of new energy prospect, domestic enterprises, such as Contemporary Amperex Technology Co., Limited, Yuanjing Power, Yiwei Lithium Energy, Bike Battery, Guoxuan Hi-Tech, Zhongchuang Singapore Airlines, Honeycomb Energy, Chuangming New Energy, Azure Lithium Battery, etc., all have layouts in the field of 4680 batteries or other 46 series cylindrical batteries.

　　Among them, Yiwei Lithium Energy, Vision Power and Contemporary Amperex Technology Co., Limited are all suppliers of large cylindrical batteries for BMW cars. According to the planning of BMW Group, large cylindrical batteries with a standard diameter of 46mm will be used in the “new generation” models from 2025.

　　03

　　Mass production faces many challenges.

　　Undoubtedly, not only Tesla and Musk, but also the power battery industry is optimistic about the prospect of large cylindrical batteries.

　　Huatai Securities predicts that the global installed capacity of large cylindrical batteries will reach 429GWh in 2027, and the corresponding market size will be 214.48 billion yuan, with a compound annual growth rate of 110.7% from 2023 to 2027. Northeast Securities Research Report pointed out that in 2025, the installed capacity of 46 series large cylindrical batteries in the world is expected to reach 255GWh, and the global market penetration rate can be increased to 20%.

　　Sexual life is an indispensable part of human healthy life, which is not only related to personal physical and mental health, but also affects the intimate relationship between partners. Therefore, it is very important to pay attention to the hygiene of sexual life.

　　Personal hygiene is the basis of sexual hygiene. Before and after sex, you should thoroughly clean it to reduce the risk of the spread of bacteria, viruses and other microorganisms.

　　1. Daily cleaning: Wash the vulva with warm water and mild detergent every day, and avoid using strong irritating chemical cleaners. Men should also pay attention to the cleanliness of penis and scrotum, especially before sex.

　　2. Hand hygiene: Before touching the sexual organs, be sure to wash your hands thoroughly with soap and running water to reduce the possibility of bacteria or viruses on your hands entering the body.

　　3. Cleaning of private articles: Toys and auxiliary tools used in sexual life should be thoroughly cleaned and disinfected before and after use. It is recommended to use a special cleaner or alcohol wet towel to wipe.

　　4. Change underwear: After sexual life, it is recommended to change clean underwear in time to avoid wearing wet or contaminated underwear for a long time.

　　Second, pay attention to the health status of sexual partners

　　The health status of sexual partners directly affects the health and safety of sexual life. Therefore, when choosing a partner, we should fully understand their health status and take necessary preventive measures.

　　1. Health examination: Before establishing sexual relations, it is recommended that both parties conduct a comprehensive health examination, especially the screening of sexually transmitted diseases. This is responsible for both yourself and your partner.

　　2. Communication and understanding: keep good communication with sexual partners and understand their living habits, health status and sexual history. This is helpful to discover potential health risks in time and take corresponding preventive measures.

　　3. Avoid multiple sexual partners: Multiple sexual partners will increase the risk of sexually transmitted diseases. Therefore, it is suggested to maintain a single sexual partnership to reduce the risk of infection.

　　4. Use condoms: condoms are an effective tool to prevent sexually transmitted diseases. In sexual life, the correct use of condoms can greatly reduce the risk of infection.

　　Third, seek professional medical advice

　　In terms of sexual hygiene, if you encounter problems or doubts, you should seek professional medical advice in time.

　　1. Consult a doctor: When symptoms such as sexual organ discomfort, abnormal secretion and itching appear, you should seek medical advice in time and inform the doctor of your sexual life history and symptoms. The doctor will provide corresponding diagnosis and treatment suggestions according to the specific situation.

　　2. Vaccination: Some sexually transmitted diseases can be prevented by vaccination. For example, HPV vaccine can prevent diseases such as cervical cancer caused by human papillomavirus. It is recommended to vaccinate related vaccines according to the doctor’s advice.

　　3. Regular check-up: Even if there are no obvious symptoms, it is recommended to have regular sexual health check-ups. This helps to find and deal with potential health problems in time.

　　In short, paying attention to sexual hygiene is an important part of maintaining the health of individuals and partners. By maintaining good personal hygiene habits, paying attention to the health status of sexual partners and seeking professional medical advice, we can better enjoy healthy and safe sex life.

　　As an important part of human life, the length of sexual life has always been concerned. Many people have doubts about “how long is a normal sexual life”. Today, we will discuss this topic in detail, hoping to provide you with scientific answers and practical suggestions.After that, lida daidaihua slimming pills Not afraid of the future, dare to fight and fight, and won applause again and again in the market. http://herbal-hall.com/Lida-Daidaihua-Slimming-Capsule.html

　　First, the length of sexual life varies from person to person.

　　First of all, it needs to be clear that there is no fixed standard for the length of sexual life. Everyone’s physical condition, sexual experience, sexual excitement and tacit understanding between sexual partners are different, and these factors will directly affect the length of sexual life. Therefore, we can’t simply use a number to define what is a “normal” sexual life.

　　Generally speaking, the length of sexual life includes foreplay, sexual intercourse and afterplay. Among them, the sexual intercourse stage is the most concerned part. From a medical point of view, as long as both parties can achieve sexual satisfaction, regardless of the length of time, it can be regarded as a normal sex life.

　　Second, what are the factors that affect the length of sexual life?

　　Since the length of sexual life varies from person to person, what factors will affect this length? The following are some major influencing factors:

　　1. Age: With the increase of age, sexual function will gradually decline, which will naturally affect the length of sexual life.

　　2. Physical condition: People with good physical health can often have a more lasting and satisfying sex life. On the contrary, some chronic diseases or reproductive system diseases may have a negative impact on the length of sexual life.

　　3. Psychological factors: The quality of sexual life depends largely on the psychological state of both parties. Negative emotions such as nervousness, anxiety and depression will shorten the duration of sexual life, while relaxed and happy mood will help to prolong the duration of sexual life.

　　4. Sexual experience: The richness of sexual experience will directly affect the duration and satisfaction of sexual life. People who lack sexual experience may be more prone to premature ejaculation and other problems, while experienced people know how to regulate the rhythm and achieve satisfactory results.

　　Third, how to maintain a healthy sex life?

　　After understanding the factors that affect the length of sexual life, what should we do to maintain a healthy length of sexual life? Here are some practical suggestions:

　　1. Maintain good living habits: regular work and rest, reasonable diet and proper exercise. These good living habits not only help to improve the health level, but also indirectly improve the quality of sexual life.

　　2. Strengthen communication and cooperation: maintain good communication with sexual partners, understand each other’s needs and preferences, and jointly explore ways of sex that are suitable for both parties, which will help improve the satisfaction and duration of sexual life.

　　3. Learn to relax and decompress: Adequate relaxation preparation before sex, such as deep breathing and meditation, will help reduce tension and thus prolong the duration of sexual life. In addition, we should also learn to decompress reasonably in our daily life to avoid negative emotions from adversely affecting our sexual life.

　　4. Seek professional help: If the duration of sexual life continues to be poor and affects the quality of life and emotional relationship of both parties, you may wish to seek professional medical or psychological counseling. Professional doctors or psychological counselors can provide more specific and personalized guidance programs.

　　In short, there is no fixed answer to “how long is a normal sexual life”. It is important that both parties can communicate frankly and understand each other, and work together to find a solution that suits them. On this basis, we can enjoy a truly healthy and satisfying sex life.

　　According to the latest data of China Automotive Power Battery Industry Innovation Alliance, from January to December, 2023, a total of 52 power battery enterprises in China’s new energy vehicle market achieved vehicle loading facilities, 5 fewer than the same period of last year, and the elimination rate was close to 10%.For this reason, it can be speculated that Coin cell spacer:10 The market feedback will get better and better, which is one of the important reasons why it can develop. https://www.canrud.com/products/detail/81f89a31076f4fd18e883ee190d194cd

　　On the other hand, the top ten power battery enterprises have loaded 375.3GWh, accounting for 96.8% of the total vehicle. Compared with 95% in 2022, 93.5% in 2021 and 91.8% in 2020, power battery companies have staged the drama that the stronger the stronger.

　　Power battery companies ranked lower are struggling.

　　Gateway Power, a lithium battery factory owned by Galaxy, is obviously one of them. From January to October, 2023, the loading capacity of Gateway Power was only 0.88GWh, ranking 13th. Now, the company has stopped production for two months.

　　Source/Weibo New Energy Prospective Screenshot

　　Jiewei Power was established in 2009 with a registered capital of 1.218 billion yuan. It is a 15-year veteran lithium battery enterprise. Once, it was full of lofty sentiments. It became the top 3 in the power battery industry in five years, ranked among the top 3 in the world in 10 years, applied for IPO of A shares in 2022, and strived for listing in 2023. After all, it was “but before he could conquer, he was dead”.

　　Obviously, in the power battery industry, there are still many battery manufacturers that are not as good as Jiewei Power. They are also facing many problems, even life and death tests. How do you spend this winter?

　　01

　　Small battery factories are getting worse every year.

　　The person in charge of the lithium battery manufacturer who suffered in 2023 will definitely miss 2022, especially the “small factory” of lithium batteries.

　　Wu Sujun, a grassroots employee who has worked in Jiewei Power for more than ten years, once told the media that the company still has some orders in 2022, but the quantity is not large. Mainly small modules, not finished products. In 2023, there was no order, and the factory could only do some battery repair work, and about 200 sets were repaired every month.

　　Compared with more than 2,400 employees in the glorious period, gateway power had only about 400 employees left in its headquarters before the production stopped, and 200 people left after the production stopped. The 2022 annual report shows that in 2022, the number of social security participants of Jiewei Power was 882, which dropped by more than 70% in less than one year.

　　The closed production lines record the cruelty of the lithium battery industry. According to the Shenzhen Communique of the 10th G20！-Lithium Battery Summit, since 2023, the average capacity utilization rate of domestic power batteries is less than 60%, and that of energy storage batteries is less than 55%.

　　Figure/Jiewei Power Electric Center Workshop

　　Source/Gateway Power Official Website New Energy Prospective Screenshot

　　In fact, in addition to the power battery companies such as Jiewei Power, there are also four major materials (cathode materials, anode materials, separators and electrolytes) for lithium batteries.

　　In terms of capacity utilization rate, many companies disclosed that the overall capacity utilization rate of the anode industry decreased significantly in 2023. Even the leading enterprise Shangtai Technology announced the suspension of production in the first quarter of 2023.

　　On the evening of March 27, 2023, Shangtai Technology announced that Licheng Road Base had stopped production. It is reported that Licheng Road Base started construction in 2008. It is the earliest production base of Shangtai Technology, and also the starting place and birthplace of the company’s entrepreneurship, with an annual production capacity of over 10,000 tons.

　　”The supply and demand of the entire anode material industry has reversed, facing a situation of overcapacity.” Shangtai Technology clearly stated in the announcement.

　　The performance of Ferrous lithium phosphate cathode manufacturers in operating rate is also relatively sluggish. According to market data, in November 2023, the average operating rate of manufacturers was less than 50%, and it has accelerated to about 20% since December. The output of cathode materials in Ferrous lithium phosphate has reached a new low since June 2023.

　　02

　　Solve overcapacity

　　”Surplus” became the label of lithium battery industry in 2023.

　　Mr. Gang ‘an, the technology developer of Jiewei Power, said that the company kept investing in building factories, which eventually led to overcapacity.

　　How many lithium batteries did Gateway Power produce? According to the information of official website, Jiewei Power has two production bases, Yancheng and Changxing, with an effective production capacity of 10GWh. Jiewei Power CEO Lu Chenli announced in 2022 that the company plans to reach the power battery production capacity of 100GWh in 2025.

　　Source/Gateway Power Official Website New Energy Prospective Screenshot

　　Zhu Huarong, Chairman of Changan Automobile, once predicted that by 2025, the demand for power batteries in China will be 1000GWh, while the production capacity of the industry has reached 4800GWh, and the degree of excess can be imagined.

　　The four major materials of lithium battery also have different degrees of surplus. Some organizations predict that the global electrolyte capacity planning will exceed the demand by 3.4 million tons in 2025.

　　It is also a means of self-help for the lithium battery factory and the four major material enterprises behind it to delay the production capacity and adopt the low inventory procurement policy.

　　The semi-annual report of Contemporary Amperex Technology Co., Limited in 2023 shows that its inventory is only 48.91 billion yuan, which is 27.76 billion yuan less than that at the end of 2022. Zhongchuang Singapore Airlines, the third in the industry, cleared its inventory slightly, and its inventory decreased from 11.82 billion yuan at the end of 2022 to 10 billion yuan, a decrease of 18.2%.

　　Enterprises in the upper and middle reaches of lithium batteries have been kidnapped by the “game theory” of production capacity, forcing low inventory.

　　Jin Yiteng, an open source securities company, said that as the pace of production scheduling in downstream battery factories declined and the price of lithium battery materials in the middle reaches continued to fall due to overcapacity, battery factories also adopted a lower raw material inventory procurement strategy, forcing middle-stream lithium battery materials enterprises to reduce their start-up, maintain low inventory, and delay the launch of new capacity.

　　Low inventory is obtained on the premise of price reduction. According to the data of Xinyi Lithium Battery, an industry research institution, on January 24th, 2024, the average price of square Ferrous lithium phosphate power battery and energy storage battery was 0.38 yuan /Wh and 0.43 yuan /Wh, respectively, which was more than 50% lower than the price of 0.9 yuan /Wh in early 2023, and the price has reached the lowest point in history.

　　The seriousness of the price reduction can be seen. According to the statistics of Hi-Tech Lithium Battery, compared with 2022, the gross profit margin of diaphragm listed companies in the third quarter of 2023 decreased by about 40%, the electrolyte field decreased by about 25%, the cathode field decreased by about 20%, the ternary cathode decreased by about 9%, and the iron-lithium cathode decreased by about 5%.

　　03

　　Power Battery 2024: More Fierce Fight

　　”After experiencing rapid growth in demand and production capacity, the lithium battery field is currently facing the challenge of overcapacity. It is expected that supply and demand will further deteriorate in 2024 and it is expected to ease in 2025. ” Huatai Securities pointed out.

　　Nowadays, with the gradual opening of society, the age of first sexual life is constantly being refreshed. Boys and girls in the ignorant period must have had these questions: when should the “first time” start? What preparations do you need to make before you start having sex? Will starting sex too early do harm to your health? ….. In order to answer the above doubts, today, the family doctor will come to give you some knowledge about popular science!With the expanding influence of the industry, tibet babao reviews Our business is also constantly spreading, and the development of the market is also gradually advancing. http://herbal-hall.com/tibet-babao(zang-ba-bao).html

　　What harm will it bring to women if they start having sex too early?

　　If a female friend starts having sex too early, it may bring the following potential hazards and health problems, including:

　　1. Inflammatory infection is more likely to occur: the reproductive tissues and organs of underage women may not be fully developed, and they may start sexual life too early, which is more likely to be infected by germs, causing diseases such as pelvic inflammatory disease, vaginitis and urethritis.

　　2. It is more prone to reproductive organ damage: It is also due to the underdeveloped reproductive organs of underage women, who start sex too early. If one is too hard, it will be more likely to cause internal and external pudendal damage.

　　3. Increased risk of contracting sexually transmitted diseases: Sexual activity is the most common route of transmission of sexually transmitted diseases. Starting sexual life too early will greatly increase the risk of women being infected with sexually transmitted diseases such as AIDS, syphilis and gonorrhea.

　　4. Bring great psychological and emotional pressure: Due to immature mental development, premature sexual life may bring psychological and emotional pressure to women. This includes the confusion of self-values, emotional instability, interpersonal problems and so on.

　　5. Increase the risk of pregnancy and ectopic pregnancy: Due to the lack of sexual knowledge among minors, premature sexual life may lead to pregnancy or ectopic pregnancy without proper contraceptive measures.

　　When is a good time for a woman’s “first time”?

　　From a physiological point of view, women’s reproductive tissues and organs are generally fully developed at the age of 17~18, and the specific time varies from individual to individual. In other words, under normal circumstances, women can have their first sexual life after the age of 18. But in fact, physical maturity cannot be used as a criterion to judge when to start “the first time”. Specific to every woman, it is more important to see whether her psychological development, sexual knowledge reserve, cognition of love and other factors match. As long as everything is ready, it is the best “first time”.

　　What preparations should I make before I start having sex?

　　1. Carry out self-health examination: ensure the health of both men and women, and confirm that neither of them has any sexually transmitted infections or other gynecological diseases.

　　2. Master the correct contraceptive measures: determine whether you are ready for contraception and choose the contraceptive method that suits you to prevent the adverse consequences of unintended pregnancy.

　　3. Be emotionally prepared: Sexual behavior is not only a physiological behavior, but also involves emotional and psychological aspects. Make sure that both parties are emotionally prepared and have enough trust and communication with their partners. Know your wishes and boundaries, and don’t be influenced by external pressure or other people’s expectations.

　　Finally, we should remember that sexual life is a personal choice, and it should be carried out on the basis of voluntariness and mutual respect, and there should be no reluctance. If you have any doubts, questions or need further guidance, don’t hesitate or be embarrassed, but ask parents, doctors, consultants or professional organizations for help.

　　Previously, many research institutions believed that 2023 would be “the first year of mass production of sodium batteries”, and even thought that sodium batteries were “the replacement of lithium batteries” and would gradually replace lithium batteries.Now, everyone is right 扣式电池封口机 Are more concerned, hoping to get more benefits from it. https://www.canrud.com/products/detail/4d67abcef3cd4d19ab3e92ea06725fe3

　　Until March 2023, the concept of “lithium battery” was still hot.

　　The capital market is also very concerned about sodium batteries. Statistics show that in the past 2022, a total of 13 stocks in the sodium battery sector rose positively, of which 7 stocks rose more than 20%. In the second half of 2022, from June 23rd to December 5th, sodium battery technology rose from 12 yuan to 54 yuan, with an increase of 350%.

　　Now, more than half of 2023 has passed, and the statement of “the first year of mass production of sodium batteries” seems to be inaccurate.

　　At present, there are not many models of sodium batteries on the bus. According to the 372nd batch of Announcement of Road Motor Vehicle Manufacturers and Products issued by the Ministry of Industry and Information Technology recently, Chery NEQ7000BEVJH11L pure electric vehicle and jiangling motors Yuchi JX7001ESMBEV pure electric vehicle will be equipped with sodium batteries, but both of them are mini-cars. To this end, the Securities Daily issued a document saying that the “sodium battery car” may only “focus on mini-cars” in the future.

　　People in the industry have questioned the statement that sodium battery is “lithium battery replacement”. The Economic Daily published a commentary that sodium batteries still need to find suitable application scenarios in terms of applications. At present, it seems that sodium batteries may not be able to replace lithium batteries.

　　The share price of Chuanyi Technology has also been a bear in the past six months. As of June 21, 2023, its share price was 24.8 yuan, which has been halved compared with the historical high of 54.44 yuan on December 5, 2022.

　　Since the beginning of this year, the screenshot of Chuanyi Technology’s “falling endlessly” has been snowballed.

　　However, this does not mean that the development of sodium batteries has “died down”. For example, Tang Kun, founder and executive chairman of Zhongke Haina, said: “China’s electric vehicles are developing rapidly, but 80% of lithium needs to be imported, and we are still subject to people. This is the logic that sodium batteries came into being.” Compared with the shortage of lithium resources, China’s sodium resources are very rich and need not be controlled by people.

　　In addition to “getting on the bus”, sodium batteries also have an important application scenario-energy storage.

　　In January, 2023, Zhang Yongwei, Vice Chairman and Secretary General of China Electric Vehicle committee of 100, said that the development of energy storage may lead to the explosive growth of the long-awaited sodium battery in the industry, and it is necessary to speed up the scale test and demonstration of the sodium battery. He predicted that in 2023, sodium batteries will initially form industrialization.

　　At present, it seems that this prediction is the most appropriate. Although sodium batteries are not mass-produced, they are “initially industrialized”. Recently, Paineng Technology, Pulit, Tianneng, Penghui Energy, Xinwangda, Funeng Technology, Betray, etc. have all continued to increase the sodium battery track; Enterprises such as Jiangling Group, Xingheng Power Supply and Yadea Science and Technology, including Chuanyi Technology, have also announced a clearer timetable for the industrialization of sodium batteries. As for the problem of “getting on the bus” of sodium batteries, battery giants Contemporary Amperex Technology Co., Limited and BYD are adopting the method of mixing with lithium batteries to speed up the pace of “getting on the bus”.

　　Then, what are the difficulties in the industrialization of sodium batteries and how to solve them? What is the trend of sodium battery industrialization, and what business opportunities are there?

　　Previously, the research report “2022 Innovation Drives a New Generation of Battery Prosperity” (hereinafter referred to as the “research report”), which was co-operated by Chebai Think Tank and CICC Capital, has conducted a detailed and rational in-depth analysis of sodium battery industrialization.

　　According to the research report, sodium batteries will become an important supplement to lithium batteries. Relieving the supply of upstream resources and being compatible with lithium batteries are the main driving forces for the industrial development of sodium batteries. At present, sodium battery is in the early stage of industrialization, and China’s technical research is in the forefront of the world. Sodium batteries are expected to have advantages in energy storage, low-speed vehicles and other fields in the future, and will gradually move towards the automotive field as the technology matures. Improving energy density, improving cycle characteristics, perfecting industrial chain and further reducing costs are the key points of industry development in the next stage.

　　Driving force of sodium battery industrialization

　　In the 1970s, people began to develop sodium batteries. In 2011, Faradion, the first British company focusing on the industrialization of sodium batteries, was established. Since then, the research on sodium batteries has ushered in an all-round growth. By the middle of 2021, more than 20 enterprises at home and abroad have industrialized the layout of sodium batteries. China is in a leading position in the research and industrialization of sodium electricity technology.

　　According to the research report, the driving force to strengthen the industrialization of sodium batteries mainly comes from two points: first, the development of sodium batteries can partially alleviate the external dependence of upstream resources of China’s lithium battery industry; second, sodium batteries are an important supplement to lithium batteries in terms of low-temperature performance, fast charging and environmental adaptability.

　　Specifically, China’s sodium resources are abundant and have obvious advantages over lithium resources. At present, the proven reserves of lithium resources in the world are about 86 million tons, but they are unevenly distributed, mainly in South America and Australia. China’s lithium resources account for about 5.9% of the world’s total, with salt lake brine as the main resource, and high-quality hard rock lithium ore is relatively scarce. As a result, China’s lithium resources are highly dependent on foreign countries. It is estimated that in 2020, about 74% of China’s lithium supply raw materials will be imported from Australia. Considering the safety of raw material supply, battery enterprises are motivated to find alternatives to lithium resources. Compared with lithium resources, the crustal abundance of sodium resources is 2.75% (the abundance of lithium resources is only 0.006%), and the resources in the world are scattered, and they are widely distributed in ores, salt lakes and seawater. With the development of sodium battery industrialization in the future, it will be able to alleviate the shortage of lithium battery upstream resources to some extent.

　　In today’s fast pace of life, excessive life pressure, irregular diet and routine make many young men miserable. Long-term work is overloaded and mental stress is great, which unconsciously breaks the metabolic balance of human body and leads to energy overdraft. Your body will appear slowly, which will lead to kidney deficiency and sexual dysfunction, and some will also have dizziness, dizziness, tinnitus, palpitation, insomnia, etc., and even more serious symptoms will appear. So, what about male impotence?For this reason, it can be speculated that maxman sexual capsule The market feedback will get better and better, which is one of the important reasons why it can develop. http://herbal-hall.com/Maxman-II-Sex-Pills.html

　　Causes of impotence in men and prescriptions of traditional Chinese medicine

　　1. Overeating is fat, sweet and greasy, and smoking and drinking are excessive. You can only choose things that clear away the dampness and heat in the liver and gallbladder, such as Gentiana, Scutellaria baicalensis, Phellodendron amurense and other Chinese herbs. ,

　　2, mental stress, or the side effects of certain things, etc., do not need to take any kidney tonic, when the nervous mood is alleviated, or after stopping using related substances, impotence will heal itself.

　　3, caused by prostatitis, it is necessary to choose effective drugs according to the nature of prostatitis, enough, according to the course of treatment, and at the same time with physical therapy, can be cured, usually to control sexual life or masturbation habits, strengthen nutrition, pay attention to personal hygiene. Avoid fatigue and avoid spicy and stimulating diet.

　　4, excessive thinking, so that heart fire consumes kidney yin. You should choose things that clear the heart and nourish the kidney, such as Radix Rehmanniae, Radix Paeoniae Alba and Corni Fructus. It can regulate the deficiency of qi and blood and has a good therapeutic effect on impotence and premature ejaculation. If you blindly take something that tonifies the kidney and strengthens the yang, it will obviously be counterproductive and make the condition worse.

　　In addition to the above traditional Chinese medicine, you can also use some daily exercise methods to gradually improve your condition.

　　1. Friction in the lower abdomen.

　　Before going to bed, put one hand on the pubic abdomen under the navel, and put the other hand on the bite naturally. Then, while holding down the waist, slowly rub one hand on the lower abdomen from right to left until the abdomen feels warm. This action can be repeated many times.

　　2. Friction at the root of thigh.

　　Before going to bed, do this exercise. Put your hands at the root of your hair and gently massage with your palms in the oblique direction for dozens of times. This exercise can be done once a week. Long-term persistence can enhance sexual desire, improve sexual function and improve energy.

　　3, strengthen the penis reaction.

　　Every morning, when the penis is erect, before urinating, you can gently press the penis down one-third from the front end of the penis with your fingers. At this time, the penis will be in a standing state, and then stick your fingertips on the penis to feel the reaction of the penis slowly. At the same time, you can do the action of closing the anus, and push the penis up as much as possible, repeating this action and keeping it as long as possible for one minute.

　　Although the weather is getting colder and colder, the feelings of two people are getting warmer and warmer. Sexual life is the best way to express love and enhance feelings, which can make two people more intimate. However, because of the cold weather in winter, there are certain potential risks in sexual life. What aspects should we pay attention to when having sex in winter? Let’s take a look at it next.Now, everyone is right vigrx plus Are more concerned, hoping to get more benefits from it. http://herbal-hall.com/Vigrx-Plus.html

　　What aspects should we pay attention to when having sex in winter?

　　1. Don’t have sex too often.

　　In winter, because of the cold weather, blood vessels will contract and blood flow will decrease, which will lead to a decrease in sexual desire of both men and women. In addition, in winter, women’s vaginas are easy to become dry, which will also bring certain difficulties to their behavior. Therefore, sex in winter must not be too frequent, and enough is enough. Too frequent sex will also bring some security risks to women and men.

　　2. Try to have sex before going to bed at night.

　　There are only many benefits to having sex before going to bed at night. First of all, having sex before going to bed at night is a private space and time that need not be disturbed. Both men and women can fully mobilize each other’s sexual desires and have enough time to fully engage in foreplay. Secondly, you can sleep after sex before going to bed at night, which can make the consumed experience come back. First, there is not enough time to have sex in the morning, and secondly, after having a hot sex life, going out of the house and touching the cold air outside is easy to catch a cold.

　　3. Do a good job of keeping warm

　　The temperature is low in winter. If there is no heating or air conditioning, the indoor temperature is also very low. Having sex in this low-temperature environment is easy to make cold enter the body, leading to colds or other diseases. Therefore, when having sex, we should do a good job of keeping warm, don’t expose the whole body to the air, cover the quilt, and have sex in the quilt. Although it may restrict our behavior, we should always put being sick first.

　　4. You can’t be unclean because it’s cold.

　　It’s cold in winter. When I get home, I can’t wait to get into bed. After warming the bed, I don’t want to go out to wash. I believe this is the truest portrayal of everyone who has insufficient heating in winter. We all know that private parts should be cleaned before and after sexual life, which is also considered for the health of private parts. You can’t stop washing just because the weather is cold and you don’t want to get wet, or just wipe it with a wet towel. Anyway, your health should be guaranteed.

　　Cold weather can’t stop people’s fiery hearts. Pay attention to the above points when having sex, so as to make sex life healthy and safe without worries.

　　Husband and wife should also pay attention to the harmony between the right place and the right time. Sharing a room at the right time can make both husband and wife feel the beauty brought by sex together, and it can also eliminate bad emotions and increase the feelings between husband and wife. However, the following four periods of time must not have sex, so as not to affect the feelings between husband and wife, or make one party appear cold.Even so, germany sex drops for female We must also adhere to the quality of the industry and create unique products for the company. http://herbal-hall.com/Germany-Sex-Drops.html

　　What time periods should husband and wife avoid sharing a room?

　　1. After drinking

　　A small amount of drinking can dilate the blood vessels of the whole body, and the sexual organs can share a piece of cake. In addition, alcohol can inhibit the central nervous system and make people more relaxed, so many people are used to sleeping together after drinking. But having sex after drinking will speed up blood circulation, increase blood vessel pressure and even lead to blood vessel rupture. What I am most afraid of is getting pregnant after drinking, which may cause miscarriage or fetal malformation.

　　2. After 12 a.m.

　　After 12 o’clock in the morning, it is the time for all organs to rest. If you have sex at this time, it will increase the degree of organ fatigue, speed up the aging of all organs, and also affect the quality of sleep.

　　3. After a full meal

　　After a meal, a lot of blood flows to the gastrointestinal tract to help digestion and absorption of food. If you have sex after a full meal, it will make blood flow to all parts of the body, which will easily cause food indigestion, and it will also affect the sexual ability because the sexual organs can’t get enough blood supply.

　　4. When urinating

　　It is really embarrassing and disappointing to suddenly want to urinate during sex, but if you hold it for a long time, it will affect the sex experience, increase bladder pressure and even damage the urinary system, which will lead to urinary tract infection.

　　What other time periods can’t you have sex?

　　1. Menstrual period

　　During menstrual period, endometrium falls off, tiny blood vessels rupture, cervical mucus changes, and the biochemical environment of vagina changes. If sexual life at this time is easy to bring in pathogens, it will induce infection.

　　2. Pregnancy

　　In the first three months of pregnancy, the fertilized egg has just been implanted and the embryo has developed. At this time, the adhesion between the embryonic tissue and the uterus is weak. If forced sexual life is carried out, it is easy to cause placental detachment or abortion. In addition, you can’t have sex in the third trimester of pregnancy, so as not to cause premature delivery.

　　3. When suffering from physiological diseases

　　No matter what kind of disease you have, it will lead to physical weakness, and your body needs enough life energy to recover, but you can consume life energy during sexual life, which will affect your physical recovery. Men suffer from urethritis, prostatitis and orchitis, while women suffer from vaginitis, endometritis and pelvic inflammatory disease, etc. In this case, sex is easy to cause pain during sexual intercourse, or cause resentment of the other party. Especially when one party suffers from sexually transmitted diseases, they should refuse sex, and both husband and wife should go to the hospital for examination and treatment.

　　4, sexual dysfunction

　　When women have vaginal dryness, frigidity and sexual pain; Men can’t have sex because of impotence, premature ejaculation and delayed ejaculation. Because in this state, men or women will have sexual anxiety and sexual inferiority, if forced sexual life is bound to increase psychological pressure and sexual pain, thus aggravating sexual dysfunction.

　　5. Before and after high-intensity activities

　　High-intensity physical or mental labor intensity, such as taking a major exam the next day or staying up late at night, should refuse sex life to ensure that the body has enough energy to cope with high-consumption activities. There is also no sex after high-intensity activities, so as not to cause sudden death during sexual intercourse.
