The impedance of alkaline manganese cells and their relationship to cell performance . I: Interpretation of the basic impedance spectrum

The impedance characteristics of undischarged alkaline manganese cells of various sizes (LR20, LR6 and LR03) have been investigated over the frequency range 100 kHz to 1 mHz. Specially constructed reference electrode probes have been inserted into the cells in two basic positions such as to obtain a...

Summary:The impedance characteristics of undischarged alkaline manganese cells of various sizes (LR20, LR6 and LR03) have been investigated over the frequency range 100 kHz to 1 mHz. Specially constructed reference electrode probes have been inserted into the cells in two basic positions such as to obtain a complete analysis of the contribution to the total impedance from the individual cell components. It is shown that the impedance of standard cells is determined by the cathode-can assembly, the anode-separator impedance being negligible by comparison. The cathode-can impedance is further resolved into two components.
