▎ 摘　　要

NOVELTY - Forming a reduced graphene oxide/metal sulfide composite, comprises: adding a dispersion comprising graphene oxide to hydrogen peroxide solution; adding at least one metal complex or salt solution to the dispersion; precipitating at least one peroxide-rich sol onto the graphene oxide surface to form at least one more peroxide rich-metal oxide precursor-supported graphene oxide; treating the supported graphene oxide with a sulfur source; heating the treated supported graphene oxide at a first temperature to form a powder; and heating the powder at a second temperature to form the composite. USE - The method is useful for forming reduced graphene oxide/metal sulfide composite, which useful as an anode in a lithium ion or sodium ion battery (claimed). ADVANTAGE - The method: provides the reduced graphene oxide/metal sulfide composite, which is free from agglomerates of metal sulfide particles, and exhibits excellent rate capability, charging rate and cycle stability as anode material; and does not require sophisticated equipment or an autoclave, hence it is cost effective, as compared to conventional methods. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a reduced graphene oxide/metal sulfide composite formed by the method.
