Evaluation Program for Secondary Spacecraft Cells. Acceptance Tests of Eagle-Picher 20.0 Ampere-Hour Nickel-Cadmium Cells with Auxiliary Electrodes

摘要

The purpose of the test program was to insure that all cells put into the life cycle program are of high quality by the removal of cells found to have electrolyte leakage, internal shorts, low capacity, or inability of any cell to recover its open circuit voltage above 1.150 volts on the cell short test. Twenty-nine 20.0 ampere-hour nickel-cadmium spacecraft cells with auxiliary electrodes purchased from Eagle-Picher Company, Joplin, Missouri were tested.
