An advanced nickel-iron battery system is currently being developed by Westinghouse for energy storage applications which include on and off road electric vehicles, emergency standby power systems and deep water submersibles. The thrust of a present development program, sponsored by the Department of Energy under the Electric/Hybrid Vehicle Act, is to demonstrate battery system performance characteristics in an electric vehicle to achieve a 100 mile range on the SAE J227a D cycle. The 1981 nickel-iron battery performance objectives established by Westinghouse required to meet this range are: 54 wh/kg gravimetric energy density; 120 wh/l volumetric energy density; and 150 w/kg peak power density. Additional requirements are > 60% charge efficiency, selling price of $80/kWh, and 1000 cycles life to provide a system with acceptable operating life cycle cost. Demonstrated results for electrodes, cells, and batteries will be presented. These include charge/discharge voltage profiles, thermal effects on performance, power characteristics, cyclic stability, and vehicular mission profiles. The design and operating features of the battery system will also be reviewed. (ERA citation 08:026603)
