Three prototype 50 ampere-hour cells of the Air Force Wright Aeronautical Laboratories (AFWAL) design have been life-tested by the McDonnell Douglas Astronautics Company St. Louis Division (MDAC-STL). Life cycling and failure analysis data is presented in this paper for cell life of up to 17167 cycles. Changes in cell performance parameters such as capacity and end-of-discharge voltage were studied as cycling progressed. The three cells completed 17167, 2473, and 10080 cycles, respectively. All failed due to internal shorts, and were disassembled for failure analyses.
