High reversibility of the charge discharge reaction leads to the longest service life. The iron electrode has low hydrogen overvoltage. Its ionization potential and hydrogen evolution potential are very close in alkaline medium. As a result, the self discharge of this system is 1-2% of the nominal capacity at 300K [1]. The advanced Ni/Fe batteries with an energy density of 55-82 Wh/Kg [2,3] serve as power sources for electric vehicles. The electrode fabrication techniques and the performance characteristics of the 6V, 60Ah Ni/Fe battery are presented in this pape
