Abstract:

The effect on the capacities of positive and negative limiting sintered plate Ni-Cd cells of varying the KOH K2CO3 ratio of an electrolyte which is approximately 7N in total alkalinity is reported. K2CO3 contents of 24, 71 and 238 g1 were investigated. Data are also presented on the specific resistance of various KOH-K2CO3 solutions over the temperature range of 86 deg F. to -40 deg F. There was no marked difference in performance of either positive or negative capacity limiting cells with electrolyte containing 24 or 71 g1 of K2CO3. However, there was an appreciable adverse effect on the performance of cells when the carbonate content was 238 g1 K2CO3, particularly for the negative capacity limiting cells. From the results of the capacity and specific resistance measurements, it is recommended that the maximum allowable carbonate content for the electrolyte in sintered plate Ni-Cd cells be set at 100 g1 K2CO3.
