| titleOfInvention | Coated graphite lithium ion battery negative electrode material and preparation method thereof |
| abstract | The invention discloses a coated graphite lithium ion battery cathode material and a preparation method thereof, which effectively control the progress of a coating reaction by a precipitation conversion method under the condition of adding a surfactant. The graphite surface is coated with a nano-scale uniform and compact aluminum phosphate coating, and the mass of the aluminum phosphate coating accounts for 0.1 wt% to 10 wt% of the mass of the graphite. The aluminum phosphate protective layer can prevent the electrolyte from directly contacting the graphite, and meanwhile, the dissolved manganese ions are prevented from being reduced to manganese metal on the surface of the graphite again. The coating layer can improve the cycle stability of the manganese-based positive electrode material/graphite matched full battery and improve the electrochemical performance of the full battery. |
