Comparison of asymmetric current parameters influence on nickel-cadmium accumulators forming time is performed. According to the results of capacity forming of NKM-22 accumulators with thin pressed cadmium and metal-ceramic electrodes, the perspective of application of asymmetric current with parameters chosen during experiments and used in this paper is established. Waveforms giving the biggest increase of capacity comply with the most economical parameters defined om models during experiments.

The results of nickel-cadmium accumulators formation with asymmetric current, in the mode providing long life of the first cycle till the accumulator stress stops to grow, are represented. The possibility of using stress on the accumulator as criterion of charge completion is proved. Research shows efficiency of mode applying chosen criterion – consedirable decrease of charge-discharge cycles of formation while preserving given working characteristics.

Comparison of influence of asymmetric current parameters on nickel-cadmium accumulators formation process time is carried out. According to the results of capacity formation of accumulators types NKPLHC-0,5 with thin extruded electrodes, we established good perspective for application of asymmetric current with parameters chosen during experiments and applied in this paper. Current waveform which gave the biggest capacity increase, has long charging impulse and short, with wide range, discharge impulse.
