What is the purpose of lithium ion battery barrier

Lithium battery barrier is one of the four key materials of 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 functions. The excellent barrier improves the overall performance of the battery. It has important uses. The important purpose of the barrier 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, and 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. As one of the key components of lithium-ion batteries, the barrier not only cuts off the positive and negative electrodes to prevent short-circuits, but also provides the transmission channel for lithium ions. The function of the barrier not only determines the battery's interface layout, internal resistance, etc., it directly affects the battery's capacity and reincarnation performance, and especially has an important impact on the battery's safety performance. As a new generation of ceramic barriers, compared with traditional barriers, ceramic barriers have a greater improvement in heat resistance and electrolyte compatibility, etc., and have obvious improvements in battery safety and cycle performance.
