Abstract
Compositions and methods of forming battery active materials are provided. A solution of battery active metal cations and reactive anions may be blended with a fuel to yield a precursor mixture usable for synthesizing a battery active material for deposition onto a substrate. The battery active metal cations include lithium, manganese, cobalt, nickel, iron, vanadium, and the like. Reactive anions include nitrate, acetate, citrate, tartrate, maleate, azide, amide, and other lower carboxylates. Suitable fuels, which may be water miscible, may include amino compounds. Alcohols and sugars may be added to adjust carbon content and fuel combustion characteristics. An exothermic reaction is performed to convert the metals into battery active oxides.
