| 摘要 |
The present invention provides a quinone compound-graphene composite material, including quinone compound and graphene, where the quinone compound is chemically bonded on the surface of the graphene, and the quinone compound is quinone compound monomer or quinone polymer. The quinone compound-graphene composite material has high energy density, high flexibility, high conductivity, and high stability, and can be used as cathode material for preparing flexible electrode. Embodiments of the present invention further provide preparation method of quinone compound-graphene composite material, and flexible lithium secondary battery using the quinone compound-graphene composite material as cathode active material. |
