  • Patent number: 9515310
    Abstract: Methods are provided for forming films of orthorhombic V2O5. Additionally provided are the orthorhombic V2O5 films themselves, as well as batteries incorporating the films as cathode materials. The methods use electrodeposition from a precursor solution to form a V2O5 sol gel on a substrate. The V2O5 gel can be annealed to provide an orthorhombic V2O5 film on the substrate. The V2O5 film 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 V2O5 films, batteries formed using the V2O5 films have extraordinarily high energy density, power density, and capacity.
