▎ 摘  要

NOVELTY - Manufacturing graphene-silver nanowire-silicon-containing composite secondary battery anode material comprises modifying surface of the silicon particles with alkoxy silane-based surface modifier to obtain silicon particles surface-modified with alkoxy silane-based surface modifier, obtaining graphene-silver nanowire-silicon composite powder by ultrasonically dispersing silicon particles, graphene oxide, silver nanowire and lithium titanate surface-modified with the alkoxysilane-based surface modifier in a solvent, freeze-drying, pulverizing, calcining graphene-silver nanowire-silicon composite material powder, cooling, and mixing with fluorine-based polymer polymer to prepare graphene-silver nanowire-silicon-containing composite secondary battery anode material. USE - The anode material is useful for coating current collector by electrospray (claimed) for rechargeable batteries in mobile device e.g. mobile phones and notebook PCs, electric bicycles and power tools. ADVANTAGE - The anode material: reduces weight of battery; has high stability; reduces volume expansion rate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene-silver nanowire-silicon-containing composite material secondary battery anode material. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating the method for manufacturing ghraphene-silver nanowire-silicon-containing composite secondary battery anode material (Drawing includes non-English language text).
