Jump Start Manufacturers Tells About Car Power Battery Diaphragm
In the global focus on the development of new energy industries such as electric vehicles and energy storage batteries, lithium batteries have become a recognized ideal energy storage component and have received higher attention. China has also invested huge capital and policy support in the field of power batteries, and has already emerged as a striking backbone enterprise in the global battery industry such as BYD, BAK, Lishen, and AVIC Lithium. Cathode materials, anode materials, battery separators and electrolytes are the four most important raw materials for lithium batteries. Due to the high investment risk and high technical threshold, lithium battery separators have not been able to achieve large-scale domestic production and become a constraint to the development of China’s lithium battery industry. The bottleneck, especially in the field of power lithium-ion batteries with higher requirements on safety and consistency, is an insurmountable obstacle in China from the big lithium battery production country to the lithium battery production power.
The jump start manufacturers said: The main production process of lithium battery separator can be divided into dry and wet methods. The vehicle power battery has a large capacity and high safety requirements, which also requires the diaphragm to have higher strength, liquid holding capacity and safe temperature. The dry process can be in the form of a multi-layer composite. The separator has many advantages such as structural safety, uniform pores, good gas permeability, high temperature resistance, etc., and is fully satisfied with the strict requirements of the power lithium battery. Manufacturers have recognized that the diaphragm of this process is the application direction of power lithium batteries.
According to the jump start manufacturers , the global lithium battery capacity is expanding rapidly. The growth rate of the lithium battery separator capacity as the main material is lagging behind. Many battery manufacturers have indicated that the diaphragm is in short supply and the diaphragm material capacity is improved. Not only is it an urgent requirement for the development of China’s lithium battery and even the world lithium battery industry. Therefore, the emergence of more national enterprises with the same star source material as soon as possible in China is an important measure to improve the industrial chain of China’s lithium battery industry and enhance the competitiveness and sustainable development capability of China’s lithium battery manufacturers. It is also related to China’s new energy automobile industry. The key link of rapid development.
