▎ 摘　　要

NOVELTY - A nanocomposite material comprises greater than or equal to 2 layers, each layer having metal oxide bonded to graphene layer. USE - Nanocomposite material for energy storage device, preferably for lithium ion battery electrode (claimed). ADVANTAGE - The material is capable of providing homogeneous dispersion of conductive and active phases. It has specific capacity of greater than 400 mAh/g. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for forming an ordered nanocomposite material comprising providing graphene in a suspension; dispersing the graphene with a surfactant; adding metal oxide precursor; and precipitating the metal oxide and allowing the graphene and the metal oxide to organize into self assembled structures, thus forming a precipitate having a series of ordered layers.
