Modern Aspects of Electrochemistry
A nickel–metal hydride secondary battery is discharged intermittently through a switch of 30 s on/30 s off mode via an external load R r. The discharge current i g is measured during switch-on and an open-circuit voltage V oc during switch-off. In the course of discharge run, i g drops at some time by depletion of an active material within the positive electrode. The pulse shapes of i g and V oc in each on/off duration are featureless before the i g drop, satisfying the relation V oc=i g(R i+R r) (R i being the internal resistance of a battery). After the i g drop, they become time dependent; yet, the above relation still holds. It is found that V oc changes continuously through the onset times of switch-on and -off.
