Abstract

Nickel-zinc battery technology is being developed for commercial applications requiring high energy density and high power capability. Development cells have demonstrated the ability to deliver over 60 Watt-hours per kilogram at the one hour rate. Cycle life has been improved to more than 600 cycles at 80% depth of discharge by using a patented, reduced solubility zinc electrode and an improved sealed cell design. More than 8000 charge/discharge cycles at 10% depth-of-discharge have been completed. Large quantities of sealed prismatic cells have been manufactured, including a 140 cell, 220 V battery for a hybrid electric vehicle (HEV)
