Bicell battery apparatus

摘要

In one implementation, a bicell battery apparatus includes first and second counter electrodes and an intermediate electrode positioned therebetween. Respective end edges of the first and second counter electrodes are received outwardly beyond a respective end edge of the intermediate electrode at a region. A current collector extension extends from one of the end edges of the intermediate electrode within the region and extends outwardly beyond the respective end edges of the first and second counter electrodes within the region. A first substantially electrolyte impermeable insulative layer is received between the current collector extension and the first counter electrode. A second substantially electrolyte impermeable insulative layer is received between the current collector extension and the second counter electrode.
