The Space Station Electrical Power System will use 1800 nickel-hydrogen battery cells in its photovoltaic power subsystem to provide energy storage for eclipse and contigency operation. This paper describes the design considerations for these 81 Ah cells, including the critical parameters that must be selected and controlled in order to ensure satisfactory battery performance over the 6,5-year life goal. These include nickel electrode void volume, loading levels, current density, chemical and mechanical parametres. Other key cell design factors related to oxygen management, mechanical and thermal design, and pressure vessel material integrity are reviewed. The baseline design will undergo significant refinement during a carefully structured development and verification process aimed at maximizing information in a limited amount of time to support a sound design decision. The discussion of this plan reviews the mass, life, and producibility trade approach. Producibility aspects are emphasized, including the necessary product and process controls and documentation requirements that must be imposed to ensure reliable, reproducible cell production.
