The role of FeS and (NH4)2CO3 additives on the pressed type Fe electrode

In the present work the influence of the FeS and (NH4)2CO3 additives on the Ni–Fe battery negative plate was studied through galvanostatic and potentiostatic discharges. Some aspects of the Fe electrode discharge mechanism in the presence of the FeS were elucidated. The presence of (NH4)2CO3 as pore forming agent in the Fe electrode was advantageous since it increased the capacity.
