AUXILIARY ELECTRODE FOR CHARGE CONTROL OF SEALED NICKEL-CADMIUM BATTERIES.

Abstract

As called for by the Main Experiment (16 cells and 6 spares) VCB Black auxiliary electrodes were installed in 22 cells made from V07 cells. 30% KOH corresponding to the semi-dry level was added, and the auxiliaries were pretested (1 atm. O2, room temp.) by measuring signaling circuit voltage and current for various resistances, while charging the cells at 0.35 amp. Performance was about that expected, and judged to be satisfactory. Replicability was better for top than side position. With supplemental 30% KOH (3.5 and 14 ml for wet and excess levels respectively) performance was reduced slightly for the top position but drastically for the side position. 16 cells (4 semi-dry, 2 wet, 2 excess, for both positions) were discharged completely, filled with O2, and are being conditioned, prior to making the Main Experiment tests. 22 similar cells are being made from N78 cells.
