Title: Application of Fe-Ni-W plated film electrode to Zinc–air battery
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 electrodes considering of 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.
