For a long time, in the field of cylindrical 18650 batteries, the industry-recognized capacity limit is 3500mAh. Japanese and Korean companies firmly occupy the high-end market. Only a small number of domestic manufacturers can produce small batches, and there are few breakthroughs. The R&D team of Fujian Dynavolt New Energy Technology Co., Ltd. (hereinafter referred to as "Fujian Dynavolt New Energy"), a wholly-owned subsidiary of Dynavolt Technology, has overcome difficulties and has been determined

Researchers at Argonne Labs and collaborating institutions point to 'Aggregates' for future battery performance. Keeping track of the latest scientific literature is an important part of a scientist's job, from which scientists can generate insights that may translate into major advances in the future. This figure shows the aggregates of the battery electrolyte. (Image courtesy of Argonne National Laboratory) In 2018, Lei Cheng, a battery chemist at the U.S. Department of Energy's (DOE) Arg

On September 24th, Great Wall Motor revealed the concepts and innovative technologies of Dayu battery technology in detail for the first time. Cao Yongqiang, Technical Director of Dayu Battery of Great Wall Motors, said that Dayu battery technology is based on the concept of "Dayu water control, better to sparse water", "change blocking to dredging", and adopts the core technical principle of "control + conduction = communication" to build 4 layers The 5-dimensional safety matrix en

Only fight for the day and night, reveal the list and take the lead. Changsha's 22 emerging and advantageous industrial chains dance strongly, becoming the main battlefield for the implementation of the "three highs and four new" strategy. Red Net Changsha Station plans the "Commanding Heights - Changsha Industrial Chain Contributions "Three Highs and Four New" Series Reports", focusing on the leading industries in the country and the world's first-class among the 22 industrial

In order to accelerate the development of new energy vehicles and promote the adjustment of energy structure, the Shanghai Municipal People's Government and CATL signed a strategic cooperation framework agreement in Shanghai on August 18. Comprehensively deepen cooperation in the field of new energy According to the "Shanghai Announcement", on the 18th, Li Qiang, Secretary of the Shanghai Municipal Party Committee, met with Zeng Yuqun, Chairman of CATL, and his party. Deputy Secretary of Shangha

After electric vehicles, the concept of electric aircraft has also entered people's field of vision. So what kind of batteries should the plane carry? According to Japanese media news on November 16, Japanese battery company GSYUASA and Kansai University have jointly developed a light-weight high-energy-density lithium-sulfur battery with a mass and energy density that can reach nearly that of existing lithium batteries. double. Relevant data show that a high energy density lithium-sulfur battery is a bat

"BYD Blade Battery has single-handedly pulled lithium iron phosphate back from marginalization," said Wang Chuanfu, chairman and president of BYD Co., Ltd. Over the years, BYD has always adhered to the lithium iron phosphate route in the field of power lithium batteries. Although some major models have also been equipped with ternary lithium batteries, this car company started with batteries, and finally changed the shape of the lithium iron phosphate power lithium battery by changing the object shape.

Cailian News Agency (Shanghai, editor Huang Junzhi), now, a key factor restricting the popularity of electric vehicles (EVs) is the "charging time". Depending on the charging method and the remaining power, electric vehicles may take several hours or a full period of time. It can be fully charged at night. This forces drivers to either be unable to travel long distances, or to find public charging stations in time and wait for a long time on long journeys.(Lithium - Ion Battery Equipment) Why does it t

Power lithium-ion battery breaks through the separator my country Chemical Industry News November 15: At present, the market supply of lithium-ion batteries in my country is seriously insufficient, and most of the market is occupied by products from the United States and Japan, resulting in high prices. After more than a decade of research and development, our production gap is now industrialized, breaking down barriers to foreign domination of our market. At the 2010 (5th) World Power Li-ion Battery Technology
