Analysis of the characteristics of ceramic-coated lithium battery separators

The characteristics 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 guard against 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. Ceramic lithium battery separators meet the following characteristics: 1. Good chemical stability; 2. High tensile strength, high puncture strength; 3. Low thermal shrinkage; high membrane rupture Temperature 4. Good compatibility with electrolyte, high liquid absorption rate 5. Prevent electrode particles from passing through, so as not to cause short circuit statement: Some pictures and content of articles published on this site are from the Internet, if there is any infringement, please contact to delete the previous article: What are the cathode materials for lithium-ion batteries
