Book Description
Research progress in the development of Ni/Fe batteries (electrodes in particular) for the period is described. The negative plate demonstrated a reliable lifetime of almost 1000 cycles; 20 mm positive plates were proved feasible; prototype cells yielded output at about 50 Wh/kg and 100 Wh/liter; program goals of 20% greater than these figures appear feasible. 27 figures, 20 tables. (RWR).

Book Description
The program has progressed to the stage of evaluating full-sized (220 Ah) cells, multicell modules, and 22 kWh batteries. Nickel electrodes that display stable capacities of up to 24 Ah/plate (at C/3 drain rate) at design thickness (2.5 mm) in tests at 200 test cycles. Iron electrodes of the composite-type are also delivering 24 Ah/plate (at C/3) at target thickness (1.0 mm). Iron plates are displaying capacity stability for 300+ test cycles in continuing 3 plate cell tests. Best finished cells are delivering 57 to 63 Wh/kg at C/3, based on cell weights of the finished cells, and in the actual designed cell volume. 6-cell module (6-1) performance has demonstrated 239 Ah, 1735 Wh, 53 WH/kg at the C/3 drain rate. This module is now being evaluated at the National Battery Test Laboratory. The 2 x 4 battery has been constructed, tested, and delivered for engineering test and evaluation. The battery delivered 22.5 kWh, as required (199 Ah discharge at 113 V-bar) at the C/3 drain rate. The battery has performed satisfactorily under dynamometer and constant current drain tests. Some cell problems, related to construction, necessitated changing 3 modules, but the battery is now ready for further testing. Reduction in nickel plate swelling (and concurrent stack electrolyte starvation), to improve cycling, is one area of major effort to reach the final battery objectives. Pasted nickel electrodes are showing promise in initial full-size cell tests and will continue to be evaluated in finished cells, along with other technology advancements. 30 figures, 14 tables.

Book Description
The objective of this program is to develop a nickel-iron battery suitable for use in electric vehicles. Ultimately, it is expected that a number of these batteries will be demonstrated under the Electric and Hybrid Vehicle Act of 1976. The report presents the technical approach and a summary of the progress that was achieved under the contract. Work began 1 May 1978. The report covers the period through September 1978. (TFD).
