✦ Synopsis
The iron-poisoning effect of sintered nickel oxide electrodes in alkaline accumulators during long-term cycling has been studied by electrochemical measurements, X-ray photoelectron spectroscopy and elemental analysis. Long-term cycling with periodic measurements of the discharge capacity, charge and discharge characteristics showed that both the quantity of iron and the way in which the iron is introduced play a large role in the poisoning.
