| titleOfInvention | Lithium ion battery anode material with conductive composite coating layer and preparation method thereof |
| abstract | The invention discloses a lithium ion battery anode material with a conductive composite coating layer, which consists of an anode active substance matrix and nano In coated on the surface of the matrix 2 O 3 And Li 2 B 4 O 7 And (4) composite layer composition. Also discloses a preparation method of the battery anode material, which has simple process route, low liquid-solid ratio of wet coating mixing and easy realization of industrial production. In one aspect, nano In 2 O 3 Has good electronic conductivity, Li 2 B 4 O 7 The lithium ion battery positive electrode material has good ionic conductivity, and the two materials have good ionic conductivity and electronic conductivity simultaneously under the synergistic effect, so that the rate capability of the positive electrode material is improved; on the other hand, nano In 2 O 3 Providing In-O bonds with large bond energy, Li 2 B 4 O 7 The electrochemical inertia can be kept in a wider voltage range, and the electrochemical inertia and the surface of the anode material are coated with the anode material in a compounding way, so that the chemical stability of the anode material can be improved. |
