▎ 摘　　要

NOVELTY - Making a 3D graphene composition, involves: associating a graphene oxide with a metal source to form a mixture; and reducing the mixture, where the method results in formation of the 3D graphene composition, and where the 3D graphene composition comprises: a reduced metal derived from the metal source; and a graphene derived from the graphene oxide, where the graphene is associated with the reduced metal. USE - The method is useful for making a 3D graphene composition used as an electrode material in an energy storage device (claimed). ADVANTAGE - The method efficiently produces a 3D graphene composition which can be used as an electrode material which enables rapid charge-discharge capability and high power density in an energy storage device. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a 3D graphene composition comprising: a graphene; and a metal associated with the graphene, where the 3D graphene composition comprises a 3D architecture.
