The nickel-iron battery system is currently being developed at Eagle-Picher Industries for use in the propulsion of electric and electric/hybrid vehicles. Eagle-Picher, through a cooperative agreement with the Swedish National Development Company has brought into the battery development program advanced iron electrode technology which is not currently available in the United States. This iron electrode technology, coupled with Eagle-Picher's nickel electrode technology and background potentially offers to the industry a battery with high specific energy, relatively low maintenance and long cycle life. The goals of the present program are to provide a battery with a storage capacity of 25-30 kWh, specific energy of 60 Wh/kg, and a cycle life in excess of 1500 cycles. Voltage levels are presently targeted to be in the 96-120 volt range. In order to meet the requirements of a vehicle battery, it has been necessary to move the nickel electrode thickness from 1.2 mm to 2.4 mm while maintaining identical loading ratios of active material. The program has also dictated the development of a thin 1.2 mm iron electrode. Development in each of these areas will be discussed in detail. Full-scale nickel-iron cells fabricated and placed under test have currently yielded energy densities in the range of 50-55 Wh/kg. Most recently six (6) volt modules have been fabricated and placed under test.
