Abstract

The formation mechanism of alkaline iron electrodes has been studied using galvanostatic polarisation techniques. An increase in electrode capacity is observed during initial charge-discharge cycling and is attributed to changes in the electrical conductivity, texture, and porosity of the active material. This is supported by an analysis of charge/discharge behaviour and also by linear and Tafel polarisation studies at various stages of formation. Results show that sulphide incorporation enhances the electrical conductivity and thereby exerts a beneficial effect on the charge-discharge characteristics.
