Lithium battery manufacturers believe that in today's global focus on the development of new energy industries such as electric vehicles and energy storage batteries, lithium batteries are recognized as the ideal energy storage components and have received higher attention. China has also invested huge funds and policy support in the field of power batteries, and has emerged BYD, BAK, Lixin, AVIC Lithium and other notable backbone enterprises in the global battery industry. Anode materials, anode materials, battery diaphragm, electrolyte is the most important four raw materials for lithium batteries, lithium battery diaphragm due to the high investment risk, high technical threshold, has not been able to achieve domestic mass production, has become a bottleneck limiting the development of China's lithium battery industry, especially in the field of safety, consistency requirements of higher power lithium-ion batteries, it is China's lithium battery production from a large country to a strong lithium battery production Insurmountable obstacles.
The main production process of lithium diaphragm can be divided into two categories: dry and wet. Automotive power battery capacity, high safety requirements, which also requires a higher strength of the diaphragm, liquid retention capacity and safety temperature. Dry process can be used in the form of multi-layer composite, the diaphragm has a safe structure, uniform pores, good air permeability, high temperature resistance and many other advantages, fully meet the strict requirements of the power lithium battery, many domestic and foreign power battery manufacturers have recognized the process of the diaphragm is the direction of application of power lithium batteries.
At present, the rapid expansion of global lithium battery production capacity, as the main material for lithium battery diaphragm production capacity growth rate is lagging behind the situation, there are many battery manufacturers have been expressed to varying degrees of diaphragm shortage, diaphragm material capacity to improve not only the development of China's lithium battery and even the world lithium battery industry is an urgent requirement. Therefore, the emergence of more national enterprises in the country as soon as possible as Star Source materials is an important step to improve the industrial chain of China's lithium battery industry and enhance the competitiveness and sustainable development of China's lithium battery production enterprises, but also about the rapid development of China's new energy vehicle industry.
