| Popis: | The impedance characteristics of different hermetic NiCd accumulators were studied in the frequency range 10 −2 –10 3 Hz during standing after charging to a pressure of 150 kPa. The pressure decreased linearly over several hours owing to oxygen reduction at the Cd electrode, and it was correlated with the low-frequency impedance of the accumulators. Based on this correlation, a method is proposed for the estimation of the pressure and rate of oxygen reduction in hermetic accumulators from the phase angle shift measured at 0.01 Hz. |
