A pole piece and lithium ion battery |
| abstract |
The present invention provides a pole piece and a lithium ion battery. A first aspect of the present invention provides a pole piece, including a substrate, the substrate includes a current collector and a protective layer disposed on the surface of the current collector, the protective layer is further provided with an active material layer; the protective layer includes 62%-96% of inactive materials, 0.1%-8% of conductive agents and 3%-30% of binders, the inactive materials include inorganic particles and organic particles, and the melting point of the organic particles is ≤180 °C. The pole piece provided by the invention can solve the problem that the safety and electrical performance of the lithium ion battery cannot be taken into account. |
