| titleOfInvention | High temperature resistant lithium battery separator, composition and preparation method thereof |
| abstract | The invention designs and prepares a cross-linked polyimide film with a higher heat resistance level in view of the problems of the limited heat resistance level of the existing lithium battery separator and the potential safety hazard of the short circuit caused by the heat damage of the separator in the lithium battery equipment. The polyimide film for lithium battery prepared by the invention contains a certain proportion of flexible segments of "alkoxy/straight-chain alkyl" structure, which greatly improves the wettability of the film to the electrolyte, and at the same time, the cross-linking agent is used for cross-linking. , while preparing micropores, it has a microscopic phase-separated structure and the alkoxy groups are complexed with lithium ions, which ensures the conduction of lithium ions and thus ensures the efficiency of the battery. The film has both the high temperature resistance of polyimide materials. It can improve the safety of lithium battery equipment. |
