What is the process technology of lithium battery diaphragm industry? Lithium-ion battery separators have complex processing techniques and high technical barriers. Lithium-ion battery separator is a critical inner layer component in a lithium-ion battery. Key properties such as battery capacity, cycle performance, and charge-discharge current density all have a direct relationship with the diaphragm, and the improvement of the performance of the diaphragm plays an important role in improving the overall performanc

What is a lithium-ion battery pack balance maintenance instrument? what is it used for? With the rapid expansion of the new energy vehicle market, the phenomenon of "squatting" in the use of urban electric buses has become prominent. This not only shortens the cruising range of new energy vehicles, but also affects the service life of electric vehicles due to the "premature aging" of battery life. Lithium-ion battery balance maintenance instrument is a portable product for dealing with outdated

The demand for lithium-ion battery management chips is strong, and the market is expected to continue to rise. With the acceleration of the popularization of mobile phone fast charging applications, the demand for accurate measurement of lithium-ion battery management chips has increased. A higher proportion of high-end mobile phones will use lithium-ion battery metering chips. In the past, some mobile phones used software to calculate battery capacity, which may not be able to meet the fast Comply with the specifi

However, du

The design and manufacturing technology requirements of aluminum-plastic film are relatively high. At present, 90% of the domestic market is mainly monopolized by Japanese and Korean companies such as DNP/Showa Denko of Japan and Kurimura of South Korea. Domestic companies such as Selen Technology and Fosu Technology are also developing Accelerate the development and processing of aluminum-plastic film, but there is still a certain gap compared with Japanese and Korean companies. At present, the packaging forms

According to foreign media reports, researchers at Hanyang University in Seoul, South Korea, have developed a lithium metal battery (LMb), in detail, a Li/NCM battery. They say the battery, designed with the operating requirements of electric vehicles in mind, outperforms lithium metal batteries previously described in the literature. The new LMb supports fast charging while delivering high energy density. With a theoretical capacity of 3860mAh/g, lithium metal is an ideal anode material for high energy density

Foreword: In recent years, the domestic fuel power cell industry has achieved remarkable development, such as Xinyuan Power, Dongfang Electric, Edelman Hydrogen Energy, Zhongyu Power, Shanghai Shenli, Jiangsu Qingneng, Jiangsu Hydrogen Power, Hydrogen Pro, Forsey, Tomorrow Hydrogen and other companies have made great progress in stack technology. At this stage, the domestic electric stack market is still dominated by foreign companies, and there is a big gap between domestic and foreign companies. Under such cir

Energy, as the material basis for the progress of human civilization, has always played an important role. It is an indispensable guarantee for the development of human society. Together with water, air, and food, it constitutes the necessary conditions for human survival and directly affects human life. . The development of the energy industry has undergone two major transformations from the "era" of firewood to the "era" of coal, and then from the "era" of coal to the "era&qu
