Holleck, G L

A storage battery with multicell arrays comprises in each cell a positive nickel electrode (cathode) spaced from a hydrogen-containing negative electrode (anode) and alkaline electrolyte medium extending between the electrodes. Further, it comprises 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 prevent electrolyte loss by entrainment in such evolved gases. An arrangement of cell construction provides recombination of free oxygen with hydrogen under safe conditions. 3 figures.
