▎ 摘  要

NOVELTY - The electrode has an electrode active material layer formed with an electrode active material. A graphene layer is formed in a side of a current collector. A conductive material is coated on the graphene layer and a binder. A conductive adhesion layer is formed on the graphene layer and the electrode active material layer, where thickness of the graphene layer is 3-30 nanometer. The conductive material is made of carbon black, acetylene black, ketjen black, activated carbon, hard carbon, soft carbon, carbon nanotube and graphite. USE - Super capacitor electrode. ADVANTAGE - The electrode has better electrode characteristic, low equivalent series resistance (ESR) and high durability. DETAILED DESCRIPTION - The binder is made of vinylidene fluoride-hexafluoropropylene copolymer, polyvinylidene fluoride, poly acrylonitrile and polymethyl methacrylate. The current collector is made of nickel, cobalt, platinum, gold, aluminum, chrome and copper. An INDEPENDENT CLAIM is also included for a method for manufacturing a super capacitor electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical view illustrating a method for manufacturing a super capacitor electrode.
