| titleOfInvention | A kind of preparation method containing PTC coating pole piece and lithium ion battery |
| abstract | The invention provides a preparation method of a pole piece containing a PTC coating and a lithium ion battery containing the pole piece, belonging to the technical field of lithium ion batteries, comprising the following steps. , 50-100 parts of high molecular polymer, 0.5-3 parts of conductive agent, after stirring evenly, add 0.1-5 parts of mixed reagent of high-voltage-resistant cross-linking agent and initiator, in which the initiator accounts for 5% of the high-voltage-resistant cross-linking agent The mass fraction is 0.1-2%, stirring for 2-8 hours to obtain coating slurry; step 2: coating the coating slurry on the current collector, drying at 80-120 ° C for 2-6 hours, to obtain coated PTC The current collector of the coating; Step 3: uniformly coat the pole piece slurry on the current collector, dry, roll, and slice to obtain a lithium ion battery pole piece containing the PTC coating. The present invention adopts the molecular design method to introduce The high-voltage cross-linked structure system can effectively improve the compatibility of the PTC coating with the pole piece and its processing performance. |
