| titleOfInvention | Phosphate-series composite cathode material and preparation method and application thereof |
| abstract | The invention relates to a phosphate composite anode material and a preparation method and application thereof, wherein the composite anode material has a core-shell structure, the core is a phosphate lithium ion battery anode material doped with metal oxide, and the shell is a coating layer consisting of nitrogen-doped titanium oxide, a composite carbon material and a transition metal oxide lithium anode material. According to the invention, by designing the coating layer which is formed by the nitrogen-doped titanium oxide, the composite carbon material and the transition metal oxide lithium anode material, the transition metal and carbon on the surface of the phosphate anode material can be coordinated through an X-C bond, so that the carbon is stably coated on the surface of the anode material, the structure can repair a lattice interface, the cycle life and the cycle stability of the anode material are enhanced, and the electrochemical performance of the material is improved. The first discharge specific capacity of the lithium ion battery at 8C multiplying power is more than 152mAh/g, and the capacity retention rate is more than 95% after 1500 times of circulation. Has good application prospect. |
