▎ 摘　　要

NOVELTY - A graphene-based electrode sheet preparing method involves mixing active material, conductive agent and graphene oxide dispersion and uniformly dispersing, adding crosslinking aid to stirring to obtain a slurry. The slurry is coated on the substrate and baked to form a film. The film is separated from the substrate to obtain the finished product. USE - Method for preparing graphene-based electrode sheet for buckle type supercapacitor (claimed). ADVANTAGE - The method enables preparing graphene-based electrode sheet with better conductivity and bonding effect.
