▎ 摘　　要

NOVELTY - A polypyrrole-coated three-dimensional graphene cobalt oxychloride lithium negative electrode material preparing method involves preparing graphene oxide based on Hummers method and purifying, dissolving graphene oxide and potassium hexacyanocobaltate in deionized water and mixing uniformly, adding cobalt chloride hexahydrate and mixing well, adding ammonium persulfate and pyrrole, stirring and mixing uniformly. The obtained product is placed in a tube furnace, heated and calcined in air, and cooled to room temperature to obtain the finished product. USE - Method for preparing polypyrrole-coated three-dimensional graphene cobalt oxychloride lithium negative electrode material. ADVANTAGE - The method provides a better experimental data and theoretical support.
