Abstract
The design and development of lightweight, common-pressure-vessel (CPV), nickel/hydrogen (Ni/H2) batteries for both low-earth-orbit (GEO) applications is discussed. The GEO design is optimized for maximum specific energy (60 Wh/kg), whereas the LEO design is optimized for cycle life (40000 cycles at 40% depth of discharge). Design considerations discussed include electrode stack components, heat transfer, sizing, mechanical design, pressure vessel design, battery construction, and the influence of these factors on specific energy and energy design. Significant design features are a 10 in diameter cylindrical pressure vessel, individual cells contained in plastic cases with hydrogen-permeable membranes, and a unique thermal and mechanical structure. A prototype 26 cell, 22 Ah aerospace CPV Ni/H2 battery has been fabricated, and performance data are presented
