▎ 摘　　要

NOVELTY - A transition metal tin oxide/graphene oxide composite material comprises nano-grade transition metal tin and graphene, and transition metal tin compound. USE - Transition metal tin oxide/graphene oxide composite material is used as lithium ion battery cathode material (claimed). ADVANTAGE - The transition metal tin oxide/graphene oxide composite material is economically prepared with improved stability, and reduced energy consumption, by simple method. DETAILED DESCRIPTION - A transition metal tin oxide/graphene oxide composite material comprises nano-grade transition metal tin and graphene, and transition metal tin compound (MSn2 or M3Sn2, where M is group VIII transition metal element). An INDEPENDENT CLAIM is included for preparation of transition metal tin oxide/graphene oxide composite material.
