▎ 摘　　要

NOVELTY - Nanocomposite material comprises graphene and a lithium-containing metal oxide on a surface of the graphene. USE - The nanocomposite material is useful as an electrode material of an energy storage device (claimed) including ultra-high capacity capacitors e.g. a lithium secondary battery and a lithium ion capacitor. ADVANTAGE - The nanocomposite material has an excellent high efficiency charge, energy density, and discharge characteristics of energy storage devices. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing a nanocomposite material, comprising preparing a metal oxide/graphene precursor by reaction of a metal oxide and graphene, and forming a lithium-containing metal oxide on a surface of the graphene by reaction of the metal oxide/graphene precursor and a lithium ion solution.
