Auxiliary Electrode for Charge Control of Sealed Nickel-Cadmium Batteries

摘要

Eighteen cells (and one replicate) have been tested in the main experiment which calls for two auxiliary positions and three quantities of electrolyte as levels of construction factors, and three rates (C/10, 1C, 5C) and three temperatures (0 F, room, 120 F) as levels of testing factors. At room temperature and 120 F signaling voltage response to pressure is generally good. At 0 F massive H2 evolution occurs on the cadmium electrode thereby causing heavy polarization of the O2-reduction electrode; as a result signaling is adversely affected and may fail to respond to O2. Statistical analysis confirms the conclusion that Side/Semi-dry is the best construction. (Author)
