Comparative Research of Asymmetric Current Parameters Influ-Ence on Accumulators Formation Process

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. In particular, application of asymmetric current with such parameters in the process of NKPLHC-0,5 accumulators formation resulted in increase of discharge capacity, compared with formation by direct current, by 16%.

Influence of Asymmetric Current Parameters on Nickel-Cadmium Accumulators Formation Process Time

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. In particular, application of asymmetric current with such parameters for NKM-22 accumulators forming gave 11% increase of discharge capacity compared with direct current forming.
