▎ 摘　　要

NOVELTY - A zinc-based complex oxide/graphene composite material comprises nano-grade zinc-based complex oxide and graphene, where the composite material has laminated structure. USE - Zinc-based complex oxide/graphene composite material for manufacturing cathode material for lithium ion battery (claimed). ADVANTAGE - The zinc-based complex oxide/graphene composite material is prepared in a simple, rapid and inexpensive manner. DETAILED DESCRIPTION - A zinc-based complex oxide/graphene composite material comprises nano-grade zinc-based complex oxide (ZnM2O4) and graphene, where M is manganese, cobalt, iron or chromium, and the composite material has laminated structure. An INDEPENDENT CLAIM is also included for a method for preparing zinc-based complex oxide/graphene composite material.
