EXTENDED LIFE NICKEL-HYDROGEN STORAGE CELL

摘要

A nickel-hydrogen electrical storage cell contains a nickel positive electrode, a hydrogen negative electrode, a separator between the electrodes, an electrolyte including rubidium hydroxide and cesium hydroxide, and a pressure vessel to contain these elements. The cell is expected to operate for extended cycle life in deep discharge conditions based upon extrapolations of accelerated life testing results. The electrolyte may be essentially entirely rubidium hydroxide or cesium hydroxide, a mixture of the two, or a mixture with another component.
