The present invention provides a nanocomposite material including graphene, a metal oxide containing lithium formed on the surface of the graphene, a manufacturing method thereof, and an energy storage device including the nanocomposite material as an electrode material. A metal oxide / graphene precursor is produced by reacting a metal oxide with graphene, and a lithium ion solution is reacted with the metal oxide / graphene precursor to oxidize lithium-containing metal on the surface of the graphene. Form things. [Selection] Figure 2 |
