▎ 摘　　要

NOVELTY - A nitrogen-doped porous carbon coated nano-nickel cobaltite electrode active material comprises nickel cobaltite modified graphene, 1,5-naphthalenediamine and perylene-3,4,9,10-tetracarboxylic dianhydride in mass ratio of 4-10:1:2.2-2.5. USE - Nitrogen-doped porous carbon coated nano-nickel cobaltite electrode active material. ADVANTAGE - The nitrogen-doped porous carbon coated nano-nickel cobaltite electrode active material has three-dimensional conductive network which promotes the transmission and migration of electrons and enhances the conductivity of the electrode material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the nitrogen-doped porous carbon coated nano-nickel cobaltite electrode active material, which involves using nickel cobaltite modified graphene, N,N-dimethylformamide, 1,5-naphthalenediamine and perylene-3,4,9,10-tetracarboxylic dianhydride.
