▎ 摘　　要

NOVELTY - Preparation of graphene-coated cobalt powder composite, involves dissolving 10,10'-dibromo-9,9'-bianthracene in tetrahydrofuran, dispersing cobalt powder in the tetrahydrofuran solution to obtain a mixed solution, volatilizing tetrahydrofuran, roasting the obtained powder mixture in an inert gas atmosphere, annealing, and cooling. USE - Preparation of graphene-coated cobalt powder composite (claimed). ADVANTAGE - The method provides graphene-coated cobalt powder composite having excellent charging/discharging effect and conductivity.
