Common-Pressure-Vessel Nickel-Hydrogen Battery Development

The dual-cell, common-pressure vessel, nickel-hydrogen configuration has recently emerged as an option for small satellite nickel-hydrogen battery application. An important incentive is that the dual-cell, CPV configured battery presents a 30 percent reduction in volume and nearly 50 percent reduction in mounting footprint, when compared with an equivalent battery of individual pressure- vessel (IPV) cells. In addition energy density and cost benefits are significant. Eagle-Picher Industries and Rockwell International have collaborated on the development and test evaluation of a 40 Ampere-hour, nickel-hydrogen, dual-cell, CPV battery module. The module was committed to a cycle life test in Rockwell\u27s advanced battery test facility. Performance and cycle life data for this first proof-of-concept module, collected over more than 6 years and 15,000 cycles of testing is presented
