Abstract

Systems and methods for producing a multilayer thin film energy storage device having a plurality of thin film battery cells arranged to provide a higher output than a single cell thin film battery. The thin film battery cells are configured so that they stacked one on another with at least one thin film battery cell positioned upside down on top of another thin film battery cell. Alternatively, the thin film battery cells may be arranged in a side-by-side configuration. Each thin film battery cell includes a thin film layer of cathode material and anode material with an electrolyte material disposed between and separating the cathode material and anode material. A thin film current collector is positioned adjacent to each cathode and anode thin film layer. The particular pattern of thin films of current collectors, anodes, electrolytes and cathodes serves to a provide a high output necessary for particular applications. The multilayer energy storage device is produced using an aligning drum system having a web of thin film cells wound therein that allows each thin film layer to be deposited onto a substrate. The output is a sheet containing a plurality of multilayer energy storage devices that can be separated from the sheet to produce an individual multilayer energy storage device. Furthermore, cutting between the stacked layers of multilayer energy storage devices produces individual thin film battery cells.
