Experiments show surprisingly substantial increase of cycle life of nickel/hydrogen cells when KOH concentration in electrolytes decreased from industry standard of 31 percent, while life decreased when concentration increased. Particularly important in view of prior recommendation to increase concentration to increase cell capacity. Benefit of increase of cycle life as concentration decreased is expected to outweigh reduction of capacity at beginning of life.
