Yearly Archives: 2025

　　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%.Sufficient data show that ncm material:10 It can drive many people to find jobs, thus driving economic development. https://www.canrud.com/products?categories=Energy+materials,Not+specified&function=Cathode

　　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.

　　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%.

　　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.

Лазерная технология имеет широкий спектр применения во многих областях, таких как промышленное производство, медицина, военное дело, научные исследования, бизнес, развлечения и т. д. В 1970-х и 1980-х годах лазеры начали использоваться для очистки поверхностей произведений искусства в разных странах. Последующие попытки использовать их для очистки поверхности культурных реликвий от мусора, как правило, в каменных культурных реликвиях с большим количеством. В настоящее время многие страны, такие как Франция, США, Великобритания, Греция, Италия и т. д., использовали лазерную технологию для реставрации культурных реликвий. Лазерная маркировочная машина

Как работает технология лазерной очистки?

Машина для лазерной очистки это использование высокоэнергетического лазерного луча для облучения поверхности объекта. Поверхностная грязь, пятна ржавчины или покрытия мгновенно испаряются или удаляются. Это приводит к чистому процессу. Лазеры обычно состоят из трех частей: резонатора, генератора света и охладителя.

Принцип работы: лазер излучает монохроматическую сильную, высококонцентрированную энергию и в одном направлении излучаемого света. Затем подключите к лазерной головке через ведущий рычаг резонатора или оптоволоконный кабель и отрегулируйте лазерную головку, чтобы завершить очистку. Поскольку лазер является монохроматическим, а направленное световое излучение очень хорошее. Поэтому можно сфокусировать луч с помощью комбинации зеркал, концентрируя луч в небольшой области или регионе. Правильное управление лазерным лучом покажет эффект очистки.

Как лазеры очищают каменные артефакты?

Поскольку поверхность каменных артефактов, грязи и камня представляет собой комбинацию слабых химических и физических сил. Слабые химические силы включают водородные связи и энергию связи, образованную переносом заряда. Физические силы включают силы Ван-дер-Ваальса (электростатические, индуцированные и дисперсионные эффекты) и капиллярные силы.

Кроме того, камень труднее чистить, чем другие материалы, из-за большого количества микропор, которые существуют в натуральном камне. Капиллярная сила микропористого пространства не только создает различные связи между грязью и камнем, но и силу связи. В то же время его эффект обволакивания также затрудняет участие в различных силах очистки.

Когда лазерный луч попадает на поверхность объекта, он может иметь по крайней мере три эффекта. Во-первых, он будет вызывать явление механического резонанса на твердой поверхности, так что поверхностный слой или конденсат оторвутся. Во-вторых, он заставит поверхностный слой грязи расшириться и преодолеть базовый материал на адсорбции частиц грязи и отделиться от поверхности объекта. В-третьих, в одно мгновение, чтобы молекулы грязи испарились, испарились или разложились.

Лазерный очиститель это использование лазерной импульсной вибрации, теплового расширения частиц, молекулярного фоторазложения или фазового перехода трех ролей. А также совместное действие для преодоления грязи и поверхности материала подложки силы сцепления, так что грязь с поверхности объекта достигает цели очистки.

　　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.As can be seen from the new data, 扣式电池壳 The market influence is also growing, and the product share is also relatively increasing, which has great potential in the future. https://www.canrud.com/products/detail/81f89a31076f4fd18e883ee190d194cd

　　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.

　　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.

　　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.

　　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%.
