The current status of aerospace Ni-H2 battery technology is reviewed. Several different Ni-H2 batteries, including a 50-Ah battery and a high-pressure 50-Ah battery, are compared with respect to energy density, energy per unit volume, structural design, and heat transfer capacity. The maximum energy density achieved is 60-1 Wh/kg for the high-pressure 50-Ah cell. The Ni-H2 batteries planned for use in the next generation of INTELSAT communications satellites should achieve 48-Wh/kg usable energy density as compared with the 39 Wh/kg of INTELSAT V batteries.
