Summary
The NASA Glenn Research Center (GRC) Electrochemistry Branch designed and built five lithium-ion battery packs for demonstration in spacesuit simulators as a part of the 2007 Desert Research and Technology Studies (D-RATS) activity at Cinder Lake, Arizona. The experimental batteries incorporated advanced, NASA-developed electrolytes and included internal protection against over-current, overdischarge and over-temperature. The 500-g experimental batteries were designed to deliver a constant power of 22 W for 2.5 hr with a minimum voltage of 13 V. When discharged at the maximum expected power output of 38.5 W, the batteries operated for 103 min of discharge time, achieving a specific energy of 130 Wh/kg. This report summarizes design details and safety considerations. Results for field trials and laboratory testing are summarized.
