Patent ID: 8410372

Claim:
A stacked battery device comprising: a plurality of opposing collector foil pairs through which a plurality of secondary cells are stacked and connected in series; a comb-shaped wiring board that has a plurality of teeth individually inserted between each of the opposing collector foil pairs and electrically connected with either one of the opposing collector foil pair, and a rod supporting the plurality of teeth and provided with an output end through which potential values at the plurality of teeth are output; and sealing members individually interposed between each of the opposing collector foil pairs to electrically insulate members of each of the collector foil pairs from each other, wherein the comb-shaped wiring board includes: a comb-shaped insulating substrate, wherein the plurality of teeth and the rod supporting the plurality of teeth are formed from the comb-shaped insulating substrate, and a wiring layer formed on the insulating substrate, wherein the wiring layer has a plurality of lead wires each individually extending from a distal end of each of the plurality of teeth to an end of the rod to deliver currents of voltages across the ones of the collector foil pairs, which are in contact with the distal ends of the plurality of teeth, and wherein the sealing members cause the distal ends of the plurality of teeth to be joined to the respective ones of the respective collector foil pairs while surrounding the distal ends of the plurality of teeth except for portions at each of which the respective one of the respective collector foil pair is provided, thereby bringing the plurality of teeth into contact with the respective ones of the respective collector foil pairs to establish electrical connections therebetween.
