Abstract
Metal-hydride electrodes made of an AB2 alloy of the composition Zr0.5 Ti0.5 V0.6 Cr0.2 Ni1.2 are studied for AC impedance behaviour at several of their state-of-charge values. Impedance data at any state-of-chargecomprisetwo RC-time constants and accordingly are analysed by using a nonlinear-least-square-fitting procedure. Resistance of the electrode and frequency maximum (f∗) of the lowfrequency semicircle are found useful for predicting state-of-charge of the metalhydride electrodes.
