Abstract:

For aircraft applications, a nickel-zinc battery has been developed which exhibits an improvement in low temperaturehigh rate performance as compared to the standard nickel-cadmium aircraft battery MS-24497-5. The nickel-zinc battery is the same size and weight as the nickel-cadmium battery, but is rated at 45 AH capacity vs. 22 AH for the nickel-cadmium. Cycle life of 200 cycles 20 amperes for 1 hour have been demonstrated in a configuration capable of delivering 1000 ampere discharge at -20 F. Nickel-zinc batteries were also manufactured for remotely piloted vehicle RPV applications to compare to existing lead-acid and silver-zinc batteries. These vehicles require a limited number of cycles at a high energy density and are a logical application of the nickel-zinc system. For missile applications, a remotely activated nickel-zinc battery has been developed to compare to the standard remotely activated silver-zinc battery. Reductions in the amount of separator needed for wet stand capability allow the nickel-zinc battery to exhibit higher capacity than the silver-zinc battery at room temperature discharge. Author
