Abstract

The effect of the Ni/Fe ratio in the anode composition of Fe-air rechargeable battery using LaGaO 3 -based oxide ion conducting electrolyte was studied in terms of the discharge performance, including discharge potential and stability of anode. A Pure Ni anode showed no potential plateau during discharge, and the cycle stability was significantly low. The highest stability and discharge potential was observed for a Ni–Fe (90:10). When the anode contained a large amount of Fe, such as those with ratio of Ni–Fe (30:70), the cycle stability was low due to the aggregation of particles with an increasing number of redox cycles.
