The objective of this program is to develop a nickel-iron battery system suitable for use in the propulsion of electric and electric/hybrid vehicles. The Near-Term Electric Vehicle Battery Development goals are: battery capacity of 25 to 30 kWh; specific energy (C/3 rate) of 60 Wh/kg; specific power of 100 W/Kg (peak) and 20 W/Kg (sustained); duty cycle of 2 to 4 hr for discharge and 4 to 8 hr for charge; energy efficiency of >60%; cost of $70/kWh (1977); and cycle life (80% DOD) of 2000 cycles. The program as conducted in FY 1981 continued to show marked progress in reaching the above referenced goals. The FY 1981 program concentrated upon the fabrication, characterization and testing of the required electrodes together with the assembly and testing of full-scale cells and 6 volt (270 Ah) modules. The FY 1981 program was structured to advance the technical aspects of the nickel-iron program while simultaneously reducing its potential future cost in both the materials and process areas. Initial full-size electrodes reached 2300 cycles, full-scale, 270 Ah cells exceeded 800 cycles, and five-cell, 6 volt modules reached 725 cycles during the reporting period. All tests are presently on-going. Based on the fade rate experienced to date, lifetime of the initial electrodes is expected to be 2500 cycles.
