Role of activation on the performance of the iron negative electrode in nickel/iron cells

Activated iron electrodes have been prepared by electrochemical impregnation with both mercury and sulfur. The performance of such electrodes in 10 A h nickel/iron cells has revealed that the activation exerts only a marginal influence on the discharge capacity. By contrast, ageing of the activated...

Zusammenfassung:	Activated iron electrodes have been prepared by electrochemical impregnation with both mercury and sulfur. The performance of such electrodes in 10 A h nickel/iron cells has revealed that the activation exerts only a marginal influence on the discharge capacity. By contrast, ageing of the activated electrodes is harmful to discharge performance.
