Abstract
A method and apparatus for forming an electrochemical layer of a thin film battery is provided. A precursor mixture comprising electrochemically active precursor particles dispersed in a carrying medium is provided to a processing chamber and thermally treated using a combustible gas mixture also provided to the chamber. The precursor is converted to nanocrystals by the thermal energy, and the nanocrystals are deposited on a substrate. A second precursor may be blended with the nanocrystals as they deposit on the surface to enhance adhesion and conductivity.
