The coated separator is an important inner component of lithium batteries. It is used to separate the positive and negative electrodes and prevent short circuits in contact between the two poles. The performance of the separator has a significant impact on the storage and safety performance of the battery. Lithium battery coated separators need to have good mechanical tensile properties and strength, good thermal and chemical stability, uniform thickness, and certain breathability. White Fused Aluminum oxide powder 1-2um works as a toughening material for coating the separator.
