▎ 摘　　要

NOVELTY - A cupric oxide-cuprous/graphene nanocomposite is obtained by forming cupric oxide-cuprous oxide in shape of hollow spherical structure using mixed composition of cupric oxide and cuprous oxide nanograins, and uniformly dispersing cupric oxide-cuprous oxide hollow nanoparticles in graphene sheet. USE - Cupric oxide-cuprous/graphene nanocomposite is used for electrode of lithium battery. ADVANTAGE - The nanocomposite having high electrochemical property is prepared by simple and economical method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for production of cupric oxide-cuprous oxide/graphene nanocomposite.
