| titleOfInvention | Conductive ceramic oxide coated lithium ion battery anode material and preparation method thereof |
| abstract | The invention discloses a conductive ceramic oxide coated lithium ion battery anode material, wherein the lithium ion battery anode material in the material is LiNi x Co y Mn x‑y 1‑ O 2 Wherein x is more than or equal to 0 and less than or equal to 1, y is more than or equal to 0 and less than or equal to 1, and the conductive ceramic oxide coating layer is LaNi a Co a 1‑ O b 3‑ And the coating layer, wherein a is more than 0 and less than 1, b is more than or equal to 0 and less than 1, a two-phase compatible area exists at the interface of the anode material and the coating layer, and the thickness of the coating layer is 2-3 nm. Also discloses a preparation method of the material, which comprises the following steps: and dispersing soluble lanthanum source, nickel source and cobalt source in a solvent, dissolving, heating and stirring to form sol, adding lithium source, stirring, uniformly dispersing the precursor of the positive electrode material in the sol, and drying and calcining to obtain the lithium-ion secondary battery. The material has good interface stability, storage performance, lithium ion diffusion performance and electronic conductivity, and the method has the advantages of simple operation, low cost and strong controllability. |
