▎ 摘 要
NOVELTY - A graphene-silicon composite comprises a graphene sheet comprising single or several graphene layers, and a silicon-containing layer formed on the graphene layers. USE - Graphene-silicon composite is used in electrical device e.g. secondary battery and capacitor (all claimed). ADVANTAGE - The graphene-silicon composite has flexible and three-dimensional structure. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of graphene-silicon composite.
