Do you know the general purpose of ceramic barriers for lithium-ion batteries?

Lithium battery ceramic barrier is one of the four key materials for lithium-ion batteries. The performance of the barrier determines the battery's interface layout, internal resistance, etc., which directly affects the battery's capacity, reincarnation, and safety performance. Function has an important purpose. The important purpose of the ceramic barrier of lithium-ion battery is to separate the positive and negative electrodes of the battery to prevent short-circuits caused by the war between the north and south poles. In addition, it also has the effect of allowing electrolyte ions to pass through. In addition, since the electrolyte is an organic solvent, the barrier must also be resistant to organic solvents. The porous layout of the ceramic partition of the lithium ion battery can store and retain the electrolyte to achieve lithium ion conductivity. The ion conduction capability of lithium-ion battery is directly related to the overall function of the battery. Its purpose of cutting off the positive and negative poles enables the battery to limit the increase in current when the battery is too charged and the temperature rises, preventing the battery from short-circuiting and causing an explosion. It has the use of self-closing micropores as a protective cover for battery users and equipment. The cost of lithium-ion batteries accounts for about 1/3 of the cost of batteries. The function of the ceramic barrier determines the battery's interface layout, internal resistance, etc., which directly affect the battery's capacity, cycle performance, and safety performance. The excellent barrier has an important purpose to improve the battery's comprehensive performance. At present, 60% to 70% of the barrier market is important to recover the wet biaxial stretching process, because the wet biaxial stretching becomes more evenly balanced in the longitudinal and transverse directions. And the wet method is mainly used for high-end barriers, and the dry method is used for low-end products.
