After hitting an all-time high of 590,000 yuan/ton at the end of November 2022, the price of battery-grade lithium carbonate fluctuated and fell all the way.Even if there are obstacles to moving forward, sodium foil:20 We should also persevere, forge ahead bravely, cut waves in the sea of the market, hang on to Yun Fan and strive for the first place. https://www.canrud.com/products/detail/3bf1b87d8f134de9a7bbdefb08cf432a

　　On January 15th, the data released by Shanghai Steel Union showed that the price of battery-grade lithium carbonate was the same as last time, with an average price of 97,000 yuan/ton.

　　On January 8, the price of battery-grade lithium carbonate fell below the 100,000 yuan/ton mark.

　　This is bad news for power battery recycling enterprises. If the price of lithium carbonate is less than 100 thousand yuan per ton, the battery recycling enterprise as a “regular army” will be unprofitable.

　　About 120,000 enterprises in China have registered the battery recycling business, while only 156 “regular army” enterprises meet the white list of the Ministry of Industry and Information Technology. The “regular army” cannot compete with the small workshops at the C end because of its high investment and low Mao Lijiao. The standardized recovery rate of power batteries for new energy vehicles in China is less than 25%.

　　However, the traditional wet recycling process is long, polluting and costly, and the laws and regulations on battery recycling in various countries are getting stricter and stricter. Power battery recycling enterprises are fighting a siege battle about technical adjustment and business model.

　　Regulations and present situation

　　With the continuous development of new energy vehicles, there is also a gradual increase in the amount of retired power batteries. The life of power batteries is 5-8 years, so it is urgent to solve the problem of recycling retired power batteries.

　　From the perspective of chemical composition, waste lithium-ion batteries contain substances, electrolytes and their conversion products, which can cause environmental pollution and even personal injury if they enter the ecology.

　　The recycling of battery materials itself has multiple economic values. After the high-end equipment is retired, lithium batteries can still meet the needs of some low-end electrical appliances and can be used step by step; Even if it is scrapped, it can no longer meet the deeper use, and the relatively rare strategic metals such as lithium, cobalt and nickel contained in it still have regenerative value. In addition, battery material recycling also has economic value in energy consumption.

　　Japan, the United States and Europe have established relatively perfect rules in legislation and market implementation system.

　　Japan started early in the recycling of used batteries. Although there is no special legislation on batteries, in the field of environmental protection law, a circular economy legislative system of “Basic Law-Comprehensive Law-Special Law” has been established.

　　As early as 1994, Japan established a relatively perfect reverse logistics battery recycling system of “battery production-sales-recycling-recycling”. Battery manufacturers independently formulated the recycling scheme of power batteries, and vehicle manufacturers played an important role in recycling used batteries.

　　The United States mainly legislates from federal, state and local levels to form a complete legal system of battery recycling management. On the market side, the recycling model is based on the extension of producer responsibility and the deposit system, and the battery recycling network is established. At the same time, the waste battery recycling enterprises sell the purified recycled raw materials to battery manufacturers at the agreed price, completing the closed loop of the recycling industry.

　　After 20 days of publicity, the new EU battery regulation “Battery and Waste Battery Regulation” came into effect on August 17, 2023, and will be enforced on February 18, 2024.

　　There are many kinds of new battery laws in the European Union. Apart from stipulating who produces and who recycles, it basically sets an “e-passport” with a higher threshold for batteries entering the European market: providing battery carbon footprint statements and labels; Set the minimum recovery rate and material recovery target; Batteries entering the European market need to be affixed with QR codes and digital passports, among which power batteries are explicitly required to have electronic records.

　　At present, there are no specific indicators for battery recycling in China similar to those in the European Union, but as a programmatic document, the “Fourteenth Five-Year Plan for Industrial Green Development” shows that a relatively complete recycling system for power batteries should be built in 2025. Since 2018, the Ministry of Industry and Information Technology has mainly adopted the method of recycling white-listed enterprises of power batteries, and at present, five batches of enterprises that meet the industrial standard conditions for comprehensive utilization of used power batteries in new energy vehicles have been released; At the same time, the “Management Measures for the Recycling of Power Batteries in New Energy Vehicles” is being accelerated.

　　With regard to the minimum recovery rate of raw materials, Article 8 of the EU’s Regulation on Batteries and Waste Batteries stipulates that by 2030, the proportion of recycled raw materials such as cobalt, lead, lithium and nickel will reach 12%, 85%, 4% and 4% respectively; By 2035, it will increase to 20%, 85%, 10% and 12%.

　　According to the data of GGII, the scarcity of global resources is expected to further increase after 2035, and the exploitable lithium, cobalt and nickel can only support the demand of that year for 35, 14 and 36 years respectively.

　　As the core strategic resources of China, lithium, cobalt and nickel are highly dependent on foreign countries.

　　According to the Global Mining Development Report 2023, in 2022, China’s imports of lithium carbonate, cobalt ore and its concentrate, and nickel ore and its concentrate all ranked first in the world.

　　Among them, lithium carbonate imports account for 54% of the total global imports, mainly from Chile and Argentina, accounting for 90% and 9% respectively; Imports of cobalt ore sand and its concentrate accounted for 91% of the total global imports, up 38% year-on-year, mainly from Congo (99.9%); Imports of nickel ore and its concentrate accounted for 92% of the total global imports, down 9% year-on-year, mainly from the Philippines (83%).

　　Many people in the industry interviewed by auto business review said that improving the recycling of power batteries can greatly alleviate the dependence on resource imports.

　　According to GGII’s forecast, it is estimated that in 2030, the recoverable lithium, cobalt, nickel and manganese resources will account for about 58%, 62%, 70% and 42% of the corresponding demand respectively.

　　Three major pain points

　　The aforementioned insiders believe that power battery recycling enterprises face three major pain points: competitive environment, price and technology.

　　According to the monthly report of power battery decommissioning data released by the secretariat of China New Energy Vehicle Power Battery Recycling Industry Collaborative Development Alliance (CABRCA) on November 20th, 2023, from January to October, 2023, a total of 139,000 tons of decommissioned power batteries were produced nationwide, with a year-on-year increase of 70.9%. Among them, Ferrous lithium phosphate accounts for more than 50%.

　　After the approval of the fifth batch of white list enterprises of the Ministry of Industry and Information Technology, the number of white list enterprises for battery recycling has reached 156, with the planned construction capacity of 9.875 million tons of waste power lithium batteries and the capacity of 4.692 million tons approved by the EIA.

　　Compared with the planning capacity of 9.875 million tons of “regular army” on the white list, the amount of decommissioned batteries of more than 100,000 tons is too small to eat at all, and there are many low-priced “small workshops” vying for supplies.

　　According to auto business review’s understanding, the players of power battery recycling enterprises generally include two categories, one is the waste end of the factory, including the main engine factory, battery factory and automobile disassembly factory, and the other is the C end, which is large and scattered. Most of the small workshops come from the C end.

　　According to the data of Fu Bao Metal Network, there are about 120,000 enterprises registered as “battery recycling” in China. According to the survey report of the State Council Development Research Center, by 2023, the standardized recovery rate of power batteries for new energy vehicles in China is less than 25%.

　　There are two main disposal methods for decommissioned power batteries. One is step-by-step utilization. The decommissioned power lithium battery is used as a carrier of electric energy in other fields, so as to give full play to the residual value, mainly by disassembling, screening and reorganizing the battery packs with degraded performance that do not meet the standards of power batteries, and finally integrating the system. Then it is used in some fields that do not require high energy density, mostly in unmanned forklifts and AGVs, low-speed electric vehicles, and user-side energy storage power stations. Companies such as BMW have taken the lead in testing and laying out these ladder utilization scenarios.

　　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.On the other hand, vigour 800mg It also brings tangible benefits to everyone and feels useful. It is a model of the industry. http://herbal-hall.com/Vigour-800mg.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.

　　Having a harmonious and regular sex life can not only make people feel happy in life, but also have many benefits for their health. However, after ten years of marriage, many people’s passion for sex life has been polished away. Sex life is like a stagnant pool. Without any waves, naturally, many benefits of sex life will not be realized. Sexual life is as dull as water, how to find the passion of the past? Let’s take a look at it next.As a representative of the industry, Maxman II Sex Pills It is necessary to set a certain example for peers and lead the way in product quality. http://herbal-hall.com/Maxman-II-Sex-Pills.html

　　Sexual life is as dull as water, how to find the passion of the past?

　　1. Leave the bedroom

　　If you have sex in a bedroom all the year round, it will give people a feeling that there is no change, and naturally it is easy to get tired of sex. If you want to get back the passion of the past, you must leave the status quo, at least from this bedroom now. If there are no children and old people at home, you can unlock other areas, such as living room, bathroom, kitchen and so on. If someone bothers you at home, the couple can sneak out on a date, and they can open a room in the hotel to rekindle their love.

　　2. Change the sex mode

　　Two people have lived together for a long time, and many people are too lazy to change. If they want to have sex, they should take a shower first, then foreplay, then use a few common postures, and finally end. This long-term sex pattern is very easy to kill people’s expectations for sex, which naturally makes sex life as passionate as doing tasks. To solve this problem, we must change the mode of sex. First of all, don’t have sex at a fixed time. If you have been having sex before going to bed at night, you can put it at noon or in the morning. Secondly, don’t always use sexy love, which was often used in the past. Nowadays, sexy love emerges one after another, and different postures have different experiences. You can learn from each other and then try. In short, don’t let yourself and your partner guess every step of your sexual life. If you can’t guess, you will naturally expect to be full.

　　3. Add some adventurous spirit to sex life.

　　Chinese people are always very introverted in their sexual life and are unwilling to express their true thoughts. This is the true feeling of most people in the face of sexual life. But if you don’t express your true thoughts and others can’t guess, naturally you won’t make your sex life particularly harmonious. If you want to rekindle your passion in sexual life, you must learn the spirit of adventure. You can meet two people to go to the field or have a car crash. It is completely possible to find a long-lost passion without affecting public order and good customs. Two people can also role-play and open the door to a new world. I believe everyone will stop.

　　4. Communicate more.

　　Communication is the best way to solve problems between husband and wife. Whether it is about sexual life or other problems about life, we should communicate and exchange more, so as to find the crux of the problem and know where to start to solve the problem. Some couples have some contradictions, and the existence of these contradictions will make them unable to devote themselves to sex life, and there is no way to get passionate, which naturally makes sex life dull as water. Two people can communicate more, solve conflicts as much as possible, at least to the point of reconciliation, so as not to be disturbed by external factors in sexual life.

　　After entering the marriage hall, the passion will be exhausted in the daily necessities, but this does not mean that it will always be like this. As long as two people work together and use these tips, I believe it is only a matter of time before they return to honeymoon passion.

　　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.With the expanding influence of the industry, 扣式电池封口机 Our business is also constantly spreading, and the development of the market is also gradually advancing. https://www.canrud.com/products/detail/4d67abcef3cd4d19ab3e92ea06725fe3

　　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.

　　Source/Jianghuai Automobile Official Website New Energy Prospective Screenshot

　　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.

　　Sexual life is a matter for two people. Only when both parties are passionate can they get high-quality sexual life. If one party feels dissatisfied, sexual life can’t reach the point of harmony. In order to improve the quality of sexual life, it is very important to know what women think about sexual life. Let’s take a look at it.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 do women really think during sex?

　　1. It is hooliganism to go straight to the subject without foreplay.

　　Foreplay is an essential process in sexual life. Only gentle and lingering foreplay can fully arouse women’s sexual desire, and women will secrete enough love liquid to facilitate men’s insertion. If you don’t do foreplay, you will come straight to the point immediately, which will easily make women unprepared and lead to the situation in vaginal dryness, which will make women suffer, and naturally they will be in a bad mood in the next sexual life.

　　2. Sexual life is insecure without cleaning.

　　Clean private organs before and after sex, and it would be best if you could take a bath. Taking a bath in advance can wash away the dirty things on your body, so that the unpleasant body odor becomes the smell of fragrant bath milk. The most important thing is that bathing in advance can prevent bacteria from being brought into women’s vagina, making women suffer from gynecological diseases. In addition, there will be oral sex in some sexual lives, and it is a sign of disrespect for women to make the other person have oral sex without cleaning. Therefore, it is best for men to take a bath beforehand to make sex life safer.

　　3. The man who evaded the responsibility of contraception did not take responsibility.

　　Everyone knows that sex is a matter for two people, so contraception is also the responsibility of two people. Many men think they won’t get pregnant, so only women are responsible for contraception. Let women take emergency contraception afterwards. This kind of emergency contraception will cause damage to women’s health, and even seriously affect women’s fertility. If women don’t take the responsibility of contraception, men don’t take it, which will lead to unexpected pregnancy, and women have to have an abortion, which is also a great harm to women’s health. Male contraceptive measures like condoms can avoid all this, and men can’t sacrifice women’s health for the pleasure of sexual life.

　　4. Don’t keep asking if you have an orgasm.

　　The physiological structure of women is different from that of men. Men can experience orgasm every time they live, but women’s orgasm can be met but not sought. Many boys are used to asking women if they have an orgasm after sex or during sex. This is a very embarrassing question. It is very uncomfortable to cheat boys into having an orgasm if they have no orgasm. Because it is difficult for women to attack men’s enthusiasm and self-esteem, they all pretend to have an orgasm and call the bed, which is really very tired.

　　When men have sex, they should also consider women’s psychological thoughts. Only by eliminating women’s concerns can women be more involved and the quality of sexual life will be improved.

　　Sexual life can be said to be an indispensable physiological behavior in people’s lives. Keeping a regular sex life every day is not only conducive to enhancing feelings, but also beneficial to both sides.

　　For male friends, keep a regular husband and wife life:

　　1. It can reduce physical and mental stress. Male friends may face all kinds of pressures in their life and work. Regular and harmonious sex life can delight their body and mind, so that the stress of body and mind can be better released.

　　2. It can reduce the risk of reproductive system diseases. Harvard University once published a study in European Urology, saying that there is a correlation between the frequency of men’s ejaculation and the occurrence of prostate malignant tumors. Men ejaculate more than 21 times a month, and their risk of prostate cancer is the lowest.

　　3. Ability to maintain sperm activity and quality. Proper frequency of sexual life helps men maintain the activity and quality of their sperm.

　　4. It can prevent sexual dysfunction. Some clinical research data point out that maintaining proper frequency of sexual life can have positive significance for reducing the occurrence of male sexual dysfunction.

　　For female friends, keep a regular husband and wife life:

　　1. It can relieve some pain. In the process of sexual life, the human body will release substances such as endorphins, which can improve pain tolerance and have a certain effect on relieving migraine and joint pain.

　　2. It can improve the daily work efficiency. In the process of sexual life, the human body will release dopamine, which will keep people in a positive mood. Therefore, proper frequency of sexual life can improve women’s work efficiency during the day.

　　3. It can improve sleep quality. Sexual life will consume a lot of physical energy, which will also help improve the quality of sleep.

　　4. It can improve human immunity. By analyzing the data of healthy women, some studies have found that the secretion of immunoglobulin substances will change in the subjects with more active sexual life, and the regulatory function of the immune system will be stronger than that of women without sexual life.

　　Without sex, what is the difference between men and women?

　　Not having sex for a long time will not only seriously affect the feelings between men and women, but also bring a series of “troubles” to the health of both sides.

　　For female friends, proper frequency of sexual life can regulate the endocrine balance in the body, but long-term lack of sexual life adjustment may affect the estrogen level, lead to abnormal skin metabolism, and then cause problems such as pigmentation and acne. In addition, there has been no sexual life, which may also lead to disuse atrophy of the reproductive system, even accompanied by vaginal dryness, itching and other discomfort symptoms.

　　For male friends, the lack of sexual life and the benign stimulation of sexual love may also lead to the disuse of sexual organs and tissues, and the muscles in the penis may atrophy or even fibrosis. In addition, because there is no external ejaculation for a long time, the sperm stays in the body for too long, and the vitality and quality may gradually decrease, and eventually even lose activity. Some research data also pointed out that if men don’t have sex for a long time, the probability of impotence will be greatly improved.

　　In fact, the sexual life between men and women also follows the principle of “using it and discarding it”. Therefore, both men and women should maintain a moderate frequency of sexual life every day, so as to better maintain their physical and mental health.
