Abstract
A method for forming a nanocomposite material, the nanocomposite material formed thereby, and a battery made using the nanocomposite material. Metal oxide and graphene are placed in a solvent to form a suspension. The suspension is then applied to a current collector. The solvent is then evaporated to form a nanocomposite material. The nanocomposite material is then electrochemically cycled to form a nanocomposite material of at least one metal oxide in electrical communication with at least one graphene layer.
Claims10
A battery formed by the process of:
- dispersing graphene with a surfactant to form a first mixture;
- providing metal oxide in solvent to form a second mixture;
- mixing the first and second mixtures to form a suspension,
- applying the suspension to a current collector,
- evaporating the suspension solvent to form an anode,
- providing a cathode and an electrolyte in electrical communication with the anode;
- electrochemically cycling the anode to form a nanocomposite material comprising at least one metal oxide in direct electrical communication with at least one graphene layer as part of the anode.
