| titleOfInvention | A kind of graphene-coated lithium-ion battery ternary positive electrode material |
| abstract | The present invention relates to the related technical field of electrode materials for lithium ion secondary batteries, and more particularly, the present invention provides a ternary positive electrode material for a graphene-coated lithium ion battery. A first aspect of the present invention provides a graphene-coated ternary positive electrode material for a lithium ion battery, the preparation of which includes a solvent-1, a positive electrode active material, and a graphene-containing slurry; wherein the graphene-containing slurry and the positive electrode The weight ratio of active substances is (0.01-8):1. In the present invention, the graphene is uniformly dispersed among the ternary positive electrode material particles, and the graphene on the surface of the ternary positive electrode plays a "fixing" role on the O atoms on the surface of the material, thereby stabilizing the material structure and inhibiting the electrolytic solution on the surface of the ternary positive electrode. Decompose and improve the cycle performance of the material, especially the high temperature cycle performance. |
