ANNUAL REPORT FOR 1983 ON RESEARCH, DEVELOPMENT, AND DEMONSTRATION OF NICKEL-IRON BATTERIES FOR ELECTRIC VEHICLE PROPULSION

The significant developments during 1983 indicate the program goals for the nickel-iron battery can be achieved. Plaque development has progressed to the point where entirely production feasible nickel sinter can be produced in thickness up to 4.0 mm. This plaque is being drawn in one continuous process for slurry application, drying, and sintering. Batteries designed for power capability possess the attributes for ehv applications. Small lightweight designs would provide 100% DOD capacity without sacrifice of cycle life while delivering the power density required for acceleration. The operating temperature range of the nickel iron battery can be extended to the region of -20 and even -30 exp 0 C with the addition of sulfide to the electrolyte. This treatment produces no apparent deleterious effects on normal temperature performance. It appears that the battery can be winterized if and when it is required. The real life cycle capability of the battery is emerging from the life cycle testing. The provisions to avoid the soft-short due to iron sludge in the region of 800 cycles are being shown to be effective. Modules are presently at cycle 1000 with tests continuing. The vent-watering system has been demonstrated to be adequate for the near term. Repeated watering does not upset the electrolyte concentration. The air dilution vent system has been shown to have a large safety margin in protection against external ignition. The nickel-iron battery has now demontrated itself to be a practical system.
