▎ 摘 要
NOVELTY - Manufacture of electrical appliance involves coating a solution comprising graphene oxide on a metal and drying the solution to form primary layer, and reducing the graphene oxide to obtain two-dimensional carbon in primary layer. The primary layer comprises graphene oxide, and is directly contacted with the metal. The electrical appliance comprises active material particles, binder and conductive auxiliary agent comprising two-dimensional carbon. USE - Manufacture of electrical appliance e.g. dry battery and storage battery including manganese battery, alkaline battery, nickel-hydride battery and lithium-ion secondary battery for electric vehicle, electric power tool, personal computer and mobile phone. ADVANTAGE - The method provides electrical appliance having excellent conductivity, with high productivity. The lithium-ion secondary battery has excellent charge and discharge characteristics.
