Abstract
An improvement in accumulator batteries having a zinc anode and an oxide cathode (e.g., nickel oxide or silver oxide cathode) is disclosed. The zinc anode and/or separator part between the anode and cathode is vibrated at a frequency and amplitude sufficient to inhibit dendrite growth on the zinc anode. The electrolyte contains excess zinc such that solid zinc oxide is present in the fully charged condition. The separator may be provided with circulation enhancement means. The resulting batteries have long life with a large number of charging and discharging cycles.
