| titleOfInvention | High-nickel ternary cathode material coated by polymer blend and preparation method thereof |
| abstract | The invention discloses a high-nickel ternary positive electrode material coated by a blending polymer and a preparation method thereof, wherein the high-nickel ternary positive electrode material is coated by the blending polymer of at least two polymers with different properties, the blending polymer is the blending polymer formed by at least one of lithium polyacrylate, lithium polymethacrylate, lithium polymaleate, poly (methyl vinyl ether-co-polymaleate) lithium and lithium polyfumarate and at least one of polyaniline, polypyrrole, polythiophene, polyacetylene, polyphenylene ethylene and polydiyne, and the high-nickel ternary positive electrode material is obtained by initiating the monomer of the blending polymer to simultaneously perform oxidative polymerization by adopting a water-soluble initiator in an acidic medium. According to the invention, a layer of blended polymer film with ion conductivity and electric conductivity is formed on the surface of the high-nickel ternary cathode material, so that the blended polymer film can resist certain moisture and inhibit the dissolution of transition metal ions in electrolyte, and has the characteristics of high specific capacity, high multiplying power and long cycle life. |
