▎ 摘　　要

NOVELTY - The material comprises a metal nano particle whose outer side is coated with carbon. Graphene is dispersed in an inner side of the metal nano particle for forming a uniform network at an interval of the metal nano particle. The metal nano particle reacts with lithium. Total weight of the metal nano particle is specific weight percentage. The metal nano particle is selected from any one among silicone, tin, arsenic, germanium, bismuth, aluminum, indium, lead or gallium. Size of the metal nano particle is specific range. USE - Nano particle-graphene-carbon composite material for an electrode of a secondary battery that is utilized in an electronic device and a power storage system (all claimed). ADVANTAGE - The material effectively forms the uniform network in the metal nano particle so as to provide better conductivity. The material effectively prevents coherence between the metal nano particle and another metal nano particle due to electro chemical reaction. The material has prolonged life time. The material disperses the graphene in the inner side of the metal nano particle in a uniform manner. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a nano particle-graphene-carbon composite material manufacturing method (2) an electronic device (3) a power storage system. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a nano particle-graphene-carbon composite material.'(Drawing includes non-English language text)'
