Open-circuit potential-recovery transients of alkaline porous iron electrodes

Open-circuit, potential-time transients during the discharge of alkaline porous iron electrodes at various states-of-charge have been studied. It has been possible to arrive at a correlation between the parameters of the selfdischarge kinetics and the observed potential-recovery time constants. The study also provides a method of estimating state-of-charge of the rechargeable alkaline iron electrode
