▎ 摘 要
NOVELTY - The graphene electrode has two graphene films and an insulating medium which is set along the edge of another graphene film to form a space. An ion-liquid is filled in the formed space with several doped electrodes. The two graphene films are respectively located outside the space such that both films are not in contact with each other. USE - Graphene electrode. ADVANTAGE - The conductivity of the graphene electrode can be improved.
