▎ 摘　　要

NOVELTY - The preparation of nitrogen-doped graphene-coated nickel sulfide composite electrode material involves immersing nitrogen and sulfur-containing resin in acid solution, stirring, cleaning, crushing, drying, spreading obtained resin on the material boat, covering with nickel-based material, transferring the material boat into a high temperature furnace, heat treating under inert gas protection and collecting surface samples after completion of the reaction. USE - Preparation of nitrogen-doped graphene-coated nickel sulfide composite electrode material (claimed). ADVANTAGE - The method enables preparation of economical nitrogen-doped graphene-coated nickel sulfide composite electrode material by simple process, achieves mass productivity, enhances interaction between graphene and nickel sulfide nanoparticles, effectively inhibits the agglomeration of nickel sulfide particles and mitigates the volume expansion during the cycle.
