▎ 摘　　要

NOVELTY - Use of graphene nano-metal oxide composite material as anode material of lithium-sulfur battery, is claimed. USE - Graphene nano-metal oxide composite material for use as anode material of a lithium-sulfur battery. ADVANTAGE - The composite material has increased conductivity, large specific surface area and strong absorption energy. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing graphene nano-metal oxide composite material, which involves dispersing graphene oxide in absolute ethanol ultrasonically to obtain graphene oxide ethanol solution at a concentration of 0.1-3 mg/ml, adding 0.1-5 g nano-metal oxide in 100 ml graphene oxide ethanol solution, mixing for 0.5-4 hours to obtain graphene oxide-nano metal oxide composite suspension, followed by radiating at 100-750 mu w/cm2 using ultraviolet light, stirring the obtained graphene oxide-nano metal oxide composite suspension for 10-600 minutes for reducing graphene oxide-nano metal oxide composite suspension to obtain reduced graphene oxide-nano metal oxide composite suspension material, centrifuging and washing the obtained reduced graphene oxide-nano metal oxide composite suspension material, separating using deionized water at 20-70 degrees C for 2-120 hours to obtain the finished product.
