Abstract

Porous iron electrodes containing metal additives have been used in nickel-iron cells. The impedances of these electrodes were measured over a wide range of frequency 104 Hz to 10−2 Hz in 6 M KOH + 0·63 M LiOH solutions. Using a cylindrical pore model, porosity and its related parameters were calculated. It is found that Hg and S provide favourable porosity and thus enhance the discharge capacity.
