摘要
In the present work the influence of the FeS and (NH4)(2)CO3 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)(2)CO3 as pore forming agent in the Fe electrode was advantageous since it increased the capacity. (C) 1998 Elsevier Science S.A. All rights reserved.
