Abstract
A common mode of failure of nickel-cadmium flooded pocket plate cells is iron poisoning of the positive plate due to transfer of iron into the active material from active materials and materials of construction. Nickel plated steel pockets are sometimes used to minimize iron dissolution, particularly on the positive electrode. Sometimesα-Fe2O3 is used as an additive to the cadmium electrode. This paper assesses the extent of dissolution of iron fromα-Fe2O3 by using electron microscopy, X-ray crystallography, cyclic voltammetry, coulometric and atomic absorption measurements.
