Abstract: An ultra-thin electrochemical multi-cell energy storage device is provided within a single lightweight flexible casing. The energy storage device utilizes perforated isolating frames to form its internal structure. By adhering multi-layer current collectors to the perforated isolating frames, filling the openings formed therein with electrode material and stacking the current collectors with an electrolyte between the electrodes the assembly generated places the multiple cells in a plurality of stacks and all of the cells may be in series, parallel or some combination thereof by virtue of the assembly's construction. The external current collectors have good lateral conductivity due to their composite structure and provide for pressure insensitive interfacial contacts. The energy storage device advantageously exhibits low resistance, low ESR, and a high voltage/capacity while preferably remaining less than one millimeter thick.
