With the continuous improvement of battery capacity and performance requirements in the lithium battery market, more and more functional separator coatings have emerged, and the ultra-thin trend of lithium battery separators has become more and more obvious. In the effective space inside the battery, the ultra-thin separator can give more space for the active material of the pole piece, and can carry more functional coatings at the same time. The market demand of 5μm ultra-thin wet diaphragm in the high-end 3

Lithium batteries are widely used in cutting-edge science and technology fields such as daily electronic products, artificial intelligence, electric vehicles, and drones. But with the rapid development of lithium battery, its safety performance has become the most concerned issue. Traditional lithium batteries use liquid electrolytes, and the properties of the liquid electrolytes directly affect their safety performance. Solid-state lithium batteries can solve some of the safety problems. However, due to the low

With the rise of the new energy vehicle industry, the demand for power lithium batteries has greatly increased, but the problem is that the production of high-quality power lithium batteries is difficult to meet the market demand, while the low-end production is oversupplied. In response to this problem, on January 25, the Ministry of Industry and Information Technology revised the "Regulations for the Lithium Battery Industry" and the "Interim Measures for the Administration of Lithium Battery Indus

On June 14th, the theme lecture "Unlocking the Safety Performance of Qiantu Automobile Battery" was held at Qiantuyi Beijing Sanlitun store. Regarding the safety of power lithium batteries that consumers are most concerned about, Mr. Zhai Sheng, a technical expert of Qiantu Automobile's three electric vehicles, shared on the spot. Qiantu Motor's complete technical development path for power lithium batteries and technical solutions for battery safety performance. Mr. Zhai Sheng, General Manager

In the development of many emerging applications in the future, the key technology is inseparable from rechargeable batteries. In 2018 alone, there were 11,583 battery-related academic papers. However, the conclusions and viewpoints in many papers are exaggerated. There are two reasons for this phenomenon, one is the deliberate exaggeration of the researchers, and the other is the lack of understanding of the battery test system. Therefore, the test results in many laboratories do not represent the real situation o

Clean-energy visionaries have long argued that a better battery could reassure skeptical consumers about electric vehicle sales and make the grid better use renewable energy. However, for at least the next decade, future batteries will also be based on legacy technology. While lithium batteries already have an overwhelming lead in the battery market, rival technologies may struggle to catch up. That lead will widen as planned new lithium battery production plants come online within the next five years. Mass-p

The Qinghai Salt Lake Institute of the Chinese Academy of Sciences disclosed on the 7th that the research team of the institute has made new progress in the research on the performance of salt lake nitric acid molten salt energy storage materials, which provides more possibilities for the application of salt lake nitric acid molten salt energy storage materials in solar thermal power generation. As an emerging energy technology, solar thermal power generation technology is an important technical field in my coun

According to foreign media "Arstechnica", physicist Gabriel Veith was inspired by a substance called oobleck to develop a new chemical formula to prevent lithium batteries from catching fire. Generally speaking, the two electrodes of a lithium battery are separated by a thin piece of plastic. When the thin plastic is squeezed and ruptured, the two electrodes come into contact, causing the battery to short-circuit and eventually cause an explosion. Although a non-flammable solid electrolyte could solve

A few days ago, Narada Power and Zhejiang University signed a strategic cooperation agreement in Hangzhou. The two parties will integrate the superior resources of lithium battery research and manufacturing, and work together to actively explore the field of all-solid-state lithium battery technology. According to the cooperation agreement, in the next four years, Narada Power and Zhejiang University will conduct research and development and application of key technologies for solid-state lithium battery product
