▎ 摘 要
NOVELTY - An excellent-electrochemical performance manganese cobalt sulfide/graphene composite material is prepared by using electrochemical deposition solution comprising 5 mM cobalt (II) chloride hexahydrate, 0.75 M thiourea and 1-10 mM manganese (II) chloride hexahydrate. USE - Method for preparing excellent-electrochemical performance manganese cobalt sulfide/graphene composite material used for preparing large-area electrode material. ADVANTAGE - The method has simple operation and stable structure of prepared material.
