▎ 摘　　要

NOVELTY - Manufacture of composite material involves preparing a mixture comprising silicon, carbon nanotubes, graphene oxide and a solvent, spray-drying resultant mixture, and heat-treating. The concentration of carbon nanotube in the mixture is 0.05-0.2 wt.%. USE - Manufacture of composite material used for preparing anode of secondary battery (all claimed). ADVANTAGE - The method enables efficient manufacture of wrinkle-shaped composite material. The battery provided with the wrinkle-shaped composite material has excellent charging and discharging characteristics, and durability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for secondary battery.
