Abstract
A nickel/hydrogen storage battery comprises a nickel positive electrode having nickel oxide as a main active material, a negative electrode mainly composed of a hydrogen absorbing alloy capable of carrying out the electrochemical hydrogen absorbing and desorbing reaction, an alkaline electrolyte, and a separator, a zinc compound being contained in the nickel positive electrode, the negative electrode and the separator. The content of the zinc compound in terms of zinc oxide is 30-500 mg per Ah of battery capacity in the nickel positive electrode and 0.3-15 mg in the negative electrode and the separator. Thus, the expansion of the nickel positive electrode can be inhibited and the electrolyte retention of the negative electrode and the separator can be improved and the cycle life of the battery can be prolonged.
