Characterization of the 20-Ah nickel--cadmium cell used for energy storage on the Orbiting Astronomical Observatory
Technical Report
·
OSTI ID:7088375
Tests were conducted on 20-Ah sealed nickel--cadmium cells to evaluate initial and long-term performance at various charge rates, temperatures, and voltage-control levels. An average ampere-hour recharge of 103 percent per orbit at 13 C was able to maintain cell capacity; required watt-hour recharge on an orbital basis was 8 to 10 percent greater than required ampere-hour recharge. Cells exhibited an early life burn-in characteristic. A discharge after periods of repetitive cycling yielded two voltage plateaus, which were temporarily eliminated by the discharge.
