A commercial-grade 1.2-V 6-Ah nickel metal hydride cell
The performance of a commercial-grade 1.2-V/6-Ah nickel/metal hydride cell is reported in terms of discharge characteristics and cycle life. The cell is comprised of compacted, metal hydride negative electrodes, made out of a stoichiometric AB(2)-Laves phase with nominal composition Zr0.5Ti0.5V0.6Cr0.2Ni1.2, and sintered nickel positive electrodes. The cell can withstand prolonged charge-discharge schedules with little deterioration in performance. The effect of varying discharge rate and temperature is also examined.
