ABSTRACT:
A formation method of nickel electrode for secondary alkaline batteries which comprises charging nickel electrodes, discharging the nickel electrodes to an amount equal to their full capacity, overdischarging the nickel electrodes under the same conditions with the previous discharging step, assembling a cell with the nickel electrodes and zinc anodes and alternating the cell between charging and discharging. Property deviations among the obtained battery articles are much reduced, so that batteries can be manufactured with uniform properties. The overdischarge of the nickel electrodes ahead of the cell assembling prevents the separator from being oxidized by gas generation. Further, the charging step subsequent to assembling the cell with the overdischarged nickel electrodes and the zinc electrodes forms metal zinc components, which act as an extra capacity for the zinc electrodes, so that each battery can always secure a constant extra capacity for the zinc electrode, contributing to uniformity of properties.
