| titleOfInvention | A lithium ion battery composite pole piece and its preparation method and lithium ion battery |
| abstract | The invention relates to a lithium ion battery composite pole piece, a preparation method thereof, and a lithium ion battery. The lithium ion battery composite pole piece includes a current collector and an electrode material layer coated on at least one side of the current collector, a hole is opened on the surface of the electrode material layer, and the hole is filled with a conductive material, and the conductive material includes A thermally conductive material whose resistance increases with increasing temperature. The lithium ion battery composite pole piece provided by the invention has holes on the electrode material layer, which can reduce the local stress of the material under high compaction density, reduce the risk of pole piece cracking, and improve the pole piece qualification rate and cycle performance; The conductive material is filled in the hole, so that the conductive material is in a micro-environment surrounded by electrolyte when the battery is working. The increase in resistance interrupts the chemical reaction of the battery and improves its safety performance. |
