Nickel-Zinc Batteries for Commercial Applications

This paper discusses rechargeable nickel-zinc battery development for consumer and mobile applications such as electric bicycles, scooters and hybrid and electric vehicles. Nickel-zinc battery performance has been improved through the development of a reduced solubility zinc electrode and a patented sealed cell design. Deep cycle capability has been increased to 600 cycles while maintaining a high specific energy up to 60 Watt-hours per kilogram. Nickel-zinc provides a commercially viable alternative for lead-acid, nickel-cadmium and nickel-metal hydride for many applications.
