▎ 摘　　要

NOVELTY - A graphene/metal nanowire hybrid material composition is produced by (A) preparing a catalyst metal-coated mixture mass which includes (i) mixing exfoliated graphite flakes having a thickness of 100 nm-1 mu m, or graphene sheets having a thickness of 0.34-100 nm, with source metal particles having particle diameter of 50 nm-50 mu m, to form a mixture and (ii) depositing a catalytic metal, in nanoparticle form having a size of 1-100 nm or coating having a thickness of 1-100 nm, onto surfaces of exfoliated graphite flakes or graphene sheets and/or surfaces of source metal particles, where source metal material is selected from transition metal, aluminum (Al), beryllium (Be), magnesium (Mg), calcium (Ca), alloy, and/or compound; and (B) exposing catalyst metal-coated mixture mass to high temperature environment, at 100-2500 degrees C, for a time sufficient to enable catalytic metal-assisted growth of multiple metal nanowires, having diameter or thickness of 2-100 nm, from source metal particles. USE - Production of graphene/metal nanowire hybrid material composition for electrode of lithium battery (all claimed). ADVANTAGE - The lithium-ion battery having nanowires exhibit superior cycling behavior. The nanowires are longer and smaller in diameter, and have high rate and cost-effective. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for lithium battery comprising graphene-metal nanowire hybrid material composition as anode active material. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of the preparation of metal nanowires from particles of the same metal material.
