Abstract:

This report outlines a new program toward acquiring an understanding of battery failure mechanisms for alkaline spacecraft batteries. Apparatus for simulating charge-discharge conditions for orbiting batteries is described. Experimental programs are suggested for finding new ways 1 to store, retrieve, and use battery literature, 2 to measure quantities that change as batteries age or are used, 3 to improve monitoring of batteries, 4 to make electrodes, cells, or cell components, 5to provide failure analysis procedures, and 6 to explain failure mechanisms. Additional objectives are to measure silver solubilities, to recommend accelerated life tests, to describe thermal and heat transfer properties, and to provide within the Aero Propulsion Laboratory of the U.S. Air Force at Wright-Patterson Air Force Base, Ohio, a capability for conducting failure analysis on batteries. During this report period, work commenced on all the above objectives, excepting 6 - new ways to explain failure mechanisms. Major emphasis was given to objectives 1, 2, and 3 - literature, measurement, and monitoring, but no specific work items were completed. Equipment was selected to construct a new electrode-making facility. Author
