▎ 摘　　要

NOVELTY - Manufacture of graphene-silicon nanowire hybrid porous mat involves drying a catalyst metal-containing mat, optimally-exposing the catalyst metal-containing mat to a high-temperature environment to convert the catalyst-metal-precursor to a catalyst metal, and exposing the catalyst metal-containing mat to a high-temperature environment at 300-2000 degrees C to enable a catalytic metal-catalyzed growth of multiple silicon nanowires from the silicon particles as a feed material. The silicon nanowires have diameter of less than 100 nm and length-to-diameter aspect ratio of 5 or more. USE - Manufacture of graphene-silicon nanowire hybrid porous mat used for anode of lithium battery (claimed) used in electric vehicle, renewable energy storage and smart grid applications. ADVANTAGE - The graphene-silicon nanowire hybrid porous mat provides lithium battery with high capacity, and excellent stability, durability and charging/discharging characteristics. DETAILED DESCRIPTION - Manufacture of graphene-silicon nanowire hybrid porous mat involves preparing a catalyst metal-containing mat using a composition containing graphite flakes and catalyst-metal-coated or catalyst-metal-precursor-coated silicon particles, graphene sheet and catalyst-metal-coated or catalyst-metal-precursor-coated silicon particles, catalyst-metal-coated or catalyst-metal-precursor-coated graphite flakes and silicon particles, or catalyst-metal-coated or catalyst-metal-precursor-coated graphene sheet and silicon particles, optionally binder and optionally conductive additive, optionally drying the catalyst metal-containing mat, optimally-exposing the catalyst metal-containing mat to a high-temperature environment to convert the catalyst-metal-precursor to a catalyst metal, exposing the catalyst metal-containing mat to a high-temperature environment at 300-2000 degrees C to enable a catalytic metal-catalyzed growth of multiple silicon nanowires from the silicon particles as a feed material. The silicon particles have particle diameter of 0.2-20 mu m. The silicon nanowires have diameter of less than 100 nm and length-to-diameter aspect ratio of 5 or more. An INDEPENDENT CLAIM is included for manufacture of graphene-silicon nanowire hybrid material composition. DESCRIPTION OF DRAWING(S) - The drawing shows flowchart of manufacture of graphene-silicon nanowire hybrid porous mat.
