Lithium-ion battery separator technology is currently a pain point in China's power lithium-ion battery industry. Among the lithium-ion battery materials, the positive and negative electrode materials and electrolytes have basically reached domestic production, but the separator started late, and the technical maturity of domestic companies is not high. Although the localization rate of lithium-ion battery separators in China has been rising in recent years, it is important to occupy the low-end 3C battery separator market. The positioning rate of high-end separators is still very low. High-end 3C batteries and power lithium-ion batteries still have a large number of separators. Dependent on imports.
As we all know, in the structure of lithium-ion batteries, the separator is one of the key inner components, which not only prevents the positive and negative electrodes from contacting, but also ensures the passage of electrolyte ions. Therefore, the quality of the separator will directly affect the capacity, cycle and safety performance of the battery, and the high-quality separator has an important purpose to improve the comprehensive performance of the battery.
The common problem in the current household diaphragm is the lack of consistency, which is mainly manifested as irregular defects, unqualified porosity, uneven thickness, pore distribution and pore size distribution. In terms of porosity and pore size distribution, the domestic PP separator with uniaxial stretch is relatively close to that of foreign products. The porosity of biaxially oriented pE films is usually lower than that of foreign products, and the pore size distribution is not ideal. These issues are potential risks for the industry to be "at the mercy of others". If it cannot be solved, it may limit the healthy development of China's lithium-ion battery industry.
The separator is one of the key components of lithium-ion batteries, and the important material of the separator is porous polymer film, including polyethylene and polypropylene. Separators for lithium-ion batteries have strict requirements for safety, permeability, porosity and thickness.
