SAFT Advanced Batteries has now produced over 400 high capacity 4.5 inch Nickel Hydrogen Battery Cells for flight programs. The 4.5 inch diameter, rabbit-ear cell design is designed to provide the anticipated energy required at the lowest practical weight. SAFT has incorporated into the design our dry-powder nickel electrode, truly hermetic ceramic to metal seals, qualified terminal feedthroughs, high reliability mechanical design, composite pure platinum negative electrode, and zircar separator, plus more than 25 years experience in aerospace nickel cell technology, resulting in a 4.5 inch configuration with the 3.5 inch cell design carryover heritage. General performance requirements for GEO missions that SAFT cells meet are 15 years in orbit lifetime, 80 % DOD, low mass to energy ratios, and flexible capacity by modifying number of electrodes in the stack. This design is qualified for geostationary orbits based on SAFT's 3.5 inch qualification heritage, design verification, and cycling performed by our customer Space Systems/LORAL in support of INTELSAT VIIA and N-STAR flight programs.
