Development of the nickel-zinc battery for commercial applications

Abstract

Rechargeable nickel-zinc batteries are being developed for consumer and mobile applications such as electric bicycles, scooters and hybrid and electric vehicles. Nickel-zinc cycle life performance has been improved through the development of a reduced solubility zinc electrode. Deep cycle capability has been increased to 600 cycles while maintaining a high specific energy up to 60 Wh per kilogram. Nickel-zinc provides a commercially viable alternative for lead-acid, nickel-cadmium and nickel-metal hydride batteries for many applications.
