Life testing of secondary Ag-Zn cellsTesting on a variety of secondary silver-zinc (Ag-Zn) cells has continued at MSFC for the past six years. The latest test involves a 350 amp/hr cell design that was cycled for 12 months and has undergone approximately 5400 low-earth-orbit cycles as well as 12 deep discharges. This test is not only a life test of these cells, but it also addresses different methods of storing the cells between deep discharges. Also, impedance measurements are made on one of the packs during periodic deep discharges. It is hoped that this will give a good correlation between the health of a cell and its impedance.
