Abstract
This study was aimed at the preparation of an electrode for Zinc–air battery, which had excellent catalytic activity by use of electroplating of alloys made of abundant metal, such as Fe and Ni. The oxygen overvoltage of the Fe-Ni-W alloy plated electrode was the smallest through the measurement. The elemental composition and the enlargement of the surface area were confirmed by SEM and EDX analysis. Involvement of Fe and W of Fe-Ni-W alloy plated electrode will be one factor for its high catalytic activity. Thus plated Fe-Ni-W alloy electrodes were compared with other Fe alloy plated elec-trodes considering to their cathode performance as Zinc-air battery. The catalytic activity of Fe-Ni-W plated electrode showed the best performance comparing to Fe-Ni alloy plated electrodes as cathode for Zinc-air battery. Also comparing to the platinum electrode which had been widely used as cathode in the field of Zinc-air battery, the Fe-based alloy plated electrode showed better performance as the electrodes considering to its oxygen evolution reaction.
Highlights
World energy consumption continues to increase along with economic growth, continuing to increase at an annual average of 2.6% from 1600 GJ in 1965, reaching 5300 GJ in 2013

Summary
World energy consumption continues to increase along with economic growth, continuing to increase at an annual average of 2.6% from 1600 GJ in 1965, reaching 5300 GJ in 2013. The main energy source responsible for this huge energy consumption will be fossil fuel. Disadvantages of the society consuming such a large amount of fossil fuel have emerged as global warming and environmental pollution problems. For utilizing the renewable energy, energy storage system will be needed. Supposing electric energy as the second energy source, electric energy storage system will be indispensable
