What are the characteristics of ceramic-coated lithium battery separators?

The ceramic lithium battery separator meets the following characteristics: 1. Good chemical stability 2. High tensile strength, high puncture strength 3. Low thermal shrinkage; higher membrane rupture temperature 4. Good compatibility with electrolyte and liquid absorption rate High 5. Prevent electrode particles from passing to avoid short circuit. Features of ceramic-coated lithium battery separator 1. Thermal stability The morphology of the separator itself will not change when baked at 150 ℃, and it can effectively prevent internal short circuits and improve safety performance. 2. With the increase of the number of battery life cycles, the capacity retention rate of the ceramic diaphragm is still relatively stable. Therefore, the excellent wettability and liquid retention of the ceramic diaphragm can improve the capacity of the battery and its retention performance. 3. The stable ceramic membrane is coated with nano-TiO2 photocatalytic material. This material can slow down the accumulation and clogging of organic on the membrane surface, resist pollution, and improve the strength of the ceramic membrane tube and membrane filtration flux, so as to achieve a stable effect . 4. High mechanical properties, high tensile strength and high puncture resistance. Statement: Some pictures and content of the articles published on this site are from the Internet.
