NOVELTY - The material comprises a ternary positive electrode material core that is fixed with a core surface of a shell. The shell comprises a first coating material and a second coating material. The first coating material comprises nitrogen-doped graphene, nitrogen-doped hydrogen-containing lithium-titanium oxide and nitrogen-doped tungsten oxide. The second covering material comprises pyrolytic carbon that is formed during citric acid and polyvinyl alcohol carbonizing process. The ternary positive electrode material core comprises an un-doped nickel-cobalt lithium manganate material and nickel cobalt lithium aluminate material. USE - Coated positive electrode material. ADVANTAGE - The material improves particles contact impedance, time discharge capacity, rate performance and cycle stability.
