▎ 摘　　要

NOVELTY - The anode material has a graphene foam structure (100) that includes graphene frames connected to each other and pores between and around the graphene frames, and nanostructures (200) in the pores of graphene foam structure. The at least one of the nanostructures has a nanoparticle structure or a nanorod structure. The nanorod structure has an alloy portion at the at least one end portion thereof. USE - Anode material for secondary battery (claimed) used in electronic device such as cellular phone, laptop computer, and camcorder. ADVANTAGE - The secondary battery having largely improved charging capacity and improved durability and stability is manufactured by using the electrode material. The graphene foam structure provides conductive path having relatively high or excellent electric conductivity and very small resistance. The charging capacity of secondary battery is greatly improved, and stability and durability of the secondary battery is improved. The excellent electrical properties e.g. excellent electric conductivity or ion conductivity of the graphene foam structure is a factor for improving electrical performance of the secondary battery. The flexible secondary battery is easily manufactured by using electrode material since electrode material has flexibility. DETAILED DESCRIPTION - The at least one of nanostructures contains at least one of from silicon, germanium, tin, indium, tin sulfide, tin oxide, and ferric oxide, preferably silicon. An INDEPENDENT CLAIM is included for a method of forming an anode material for a secondary battery. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the electrode material.
