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.
EXEMPLARY CLAIMS- 1. A bicell battery apparatus, comprising:..an intermediate electrode positioned between a first counter electrode and a second counter electrode, the first and second counter electrodes each having an end edge extending outwardly beyond a corresponding end edge of the intermediate electrode; ..a single-layer first separator positioned between the first counter electrode and the intermediate electrode; ..a single-layer second separator positioned between the second counter electrode and the intermediate electrode; ..a current collector extension extending from the end edge of the intermediate electrode, and further extending outwardly beyond the end edges of the first and second counter electrodes; and ..a substantially electrolyte impermeable insulative layer positioned between the current collector extension and the first counter electrode. |
