Abstract
A process for fabrication of all-solid-state thin film batteries, may include batteries including a film of anode materials, a film of solid electrolyte materials and a film of cathode materials. Each of these three films may be deposited using an electrophoresis process. The anode film and the cathode film may each be deposited on a conducting substrate, preferably a thin metal sheet or band, or a metalized insulating sheet or band or film. The conducting substrates or their conducting elements may be useable as battery current collectors, the electrolyte film may be deposited on the anode and/or cathode film. The process may also include stacking the sheets or bands so as to form at least one battery with a “collector/anode/electrolyte/cathode/collector” type of stacked structure.
