D. Coates et al., DEVELOPMENT OF A LONG CYCLE LIFE SEALED NICKEL-ZINC BATTERY FOR HIGH ENERGY-DENSITY APPLICATIONS, IEEE aerospace and electronic systems magazine, 12(6), 1997, pp. 35-38
Nickel-zinc battery technology is being developed for commercial appli
cations requiring high energy density and high power capability. Devel
opment cells have demonstrated the ability to deliver over 60 Watt-hou
rs 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, re
duced solubility zinc electrode and an improved sealed cell design. Mo
re than 8000 charge/discharge cycles at 10% depth-of-discharge have be
en completed. Large quantities of sealed prismatic cells have been man
ufactured, including a 140 cell, 220 V battery for a hybrid electric v
ehicle (HEV).
