The research and development efforts of the program at the Westinghouse Electric Corporation on iron-air batteries during the period June 1977 to May 1978 are described. This battery is being developed as an advanced battery system for electric-vehicle propulsion. Objectives for both electrodes and cells have been established to be compatible with a final fully-engineered battery which will ultimately store greater than 140 Wh/kg and deliver greater than 100 W/kg. Work during this portion of the program has emphasized the cell testing aspects of the iron-air system along with individual electrode improvement. The cyclic voltage efficiency of 100 cm/sup 2/ size cells has been shown to be in excess of 50% with individual iron and air electrode performance characteristics comparable or superior to those characteristics established in the half cell testing program. Long-term cyclic stability for greater than 100 cycles has been established for several 100 cm/sup 2/ size cells. Work, presently underway, and tests planned in the near future, are expected to demonstrate the near-term expected performance characteristics of the iron-air cells. Additional studies are underway to improve the performance characteristics of the individual electrodes through improved processing procedures and to incorporate these improvements into the cell test program.
