▎ 摘　　要

NOVELTY - The preparation method involves adding dropwise hydrochloric acid solution to the mixed solution and continuing to stirring them before finishing reaction filtering and washing the mixture. The mixture is dried to obtain the polypyrrole/graphene composite material. The polypyrrole/graphene composite material is prepared with acetylene black. The mixture is pressed on the current collector to form an electrode material of such energy storage systems as a super capacitor. USE - Preparation method for polypyrrole/graphene composite material. ADVANTAGE - Simplifies the manufacturing process of the thus lowering the manufacturing cost. The polypyrrole in the prepared composite material is evenly covered by graphene. The composite material is used as a super capacitor thus providing high electric conductivity and good in electrochemical properties. DESCRIPTION OF DRAWING(S) - The drawing shows the picture depicting the polypyrrole/graphene composite material.
