Lithiated transition metal oxides

Abstract

Process for the fabrication of an electrode structure comprising an electrochemically active material suitable for use in an energy storage device. The method includes electrodepositing the electrochemically active material onto an electrode in electrodeposition bath containing a non-aqueous electrolyte. The electrode structure can be used for various applications such as electrochemical energy storage devices including high power and high-energy lithium-ion batteries.
