A method and apparatus for forming an electrochemical layer of a thin film battery is provided. A liquid precursor mixture comprising electrochemically active metals is reacted with oxygen to form electrochemically active metal oxides, which are deposited in a layer on a substrate. Carbon may be added to the mixture to control energy input to the reaction and to provide adhesion and conductivity between crystals deposited on the substrate. Conversion of precursors to deposition crystals may be accomplished in a two-stage process.
