Abstract
Methods are provided for forming films of orthorhombic VO. Additionally provided are the orthorhombic VOfilms themselves, as well as batteries incorporating the films as cathode materials. The methods use electrodeposition from a precursor solution to form a VOsol gel on a substrate. The VOgel can be annealed to provide an orthorhombic VOfilm on the substrate. The VOfilm can be freestanding such that it can be removed from the substrate and integrated without binders or conductive filler into a battery as a cathode element. Due to the improved intercalation properties of the orthorhombic VOfilms, batteries formed using the VOfilms have extraordinarily high energy density, power density, and capacity.
