▎ 摘　　要

NOVELTY - Manufacture of reduced graphene involves supplying a graphene oxide dispersion liquid and a reducing agent liquid containing a reducing agent for graphene oxide, from independent flow paths, and merging the liquids such that pressure of 0.3-500 MPa is set at the junction. USE - Manufacture of reduced graphene used for electrode for lithium-ion battery. Can also be used for energy storage material, electronic device, and composite material. ADVANTAGE - The method enables efficient manufacture of reduced graphene with high conductivity, high dispersibility and excellent discharge characteristics.
