A method and apparatus for forming an electrochemical layer of a thin film battery is provided. A precursor mixture comprising precursor particles dispersed in a carrying medium is activated in an activation chamber by application of an electric field to ionize at least a portion of the precursor mixture. The activated precursor mixture is then mixed with a combustible gas mixture to add thermal energy to the precursor particles, converting them to nanocrystals, which deposit on a substrate. A second precursor may be blended with the nanocrystals as they deposit on the surface to enhance adhesion and conductivity.
