▎ 摘　　要

NOVELTY - A Prussian blue/graphene/sulfur composite material is prepared by taking 0.1-0.15 g potassium ferricyanide, 5-15 mL hydrochloric acid, 3.0-3.5 g polyvinylpyrrolidone and 50-70 mL graphene oxide, carrying out hydrothermal reaction, centrifuging, drying, adding elemental sulfur, heating and melting under inert gas, and cooling. USE - Method for preparing Prussian blue/graphene/sulfur composite material used for lithium-sulfur battery anode (claimed). ADVANTAGE - The product has good conductivity and improved electrochemical performance.
