| titleOfInvention | A kind of hybrid phosphate open frame material composite high nickel cathode material and preparation method thereof |
| abstract | The invention discloses a hybrid phosphate open frame material composite high-nickel positive electrode material, and the hybrid phosphate open frame material in the composite material is uniformly coated on the surface of the high-nickel positive electrode material. A preparation method of the material is also disclosed, including: dissolving phosphoric acid, oxalic acid, V 2 O 5 and alkali metal hydroxide in deionized water, and performing a hydrothermal reaction to obtain a hybrid phosphate open frame material; Salt open frame material modification; the modified hybrid phosphate open frame material is dispersed in a non-aqueous solvent, and the high nickel cathode material is added and stirred continuously, so that the modified hybrid phosphate open frame material is coated in the high nickel cathode material. The surface of the positive electrode material is obtained. The composite positive electrode material of the invention can not only isolate the contact between the high-nickel positive electrode material and the electrolyte, reduce the occurrence of side reactions, but also increase the local specific surface area, improve the wettability of the electrolyte, increase the reactive sites, and improve the diffusion of lithium ions. kinetics, improving the stability and lithium storage performance of cathode materials. |
