Abstract
Storage battery with multi-cell arrays comprising in each cell a positive nickel electrode (cathode) spaced from a hydrogen containing negative electrode (anode) and alkaline electrolyte medium extending between the electrodes and further comprising a reservoir outside the space defined between electrodes to provide buffer storage of electrolyte displaced by gases generated in the course of cell operation, particularly during overcharging, one or more hydrophobic, microporous membranes to prevent electrolyte loss by entrainment in such evolved gases, and an arrangement of cell construction to provide recombination of free oxygen with hydrogen under safe conditions.
