Abstract
An electric storage battery having an electrochemically active cell element comprising juxtaposed positive and negative polarity electrode plates each at least partially encased in a sheath of microporous dendrite-suppressing battery separator material. Each of the sheaths is sealed along three of its peripheral borders and open on the fourth. The several plates are arranged in the cell element such that the opening in the sheaths for the positive plates face a direction opposite to the direction faced by the openings in the sheaths for the negative plates and such that the sheaths on adjacent plates overlap in the region between adjacent plates.
