Developing NiMoO4-based multifunctional cathode for hybrid zinc battery

Abstract

Herein, we developed a multifunctional cathode (Co-NiMoO₄/NF) based on nickel molybdate nanowires grown on Ni foam (NiMoO₄/NF) for a hybrid zinc-nickel (Zn–Ni) and zinc-air (Zn–Air) battery. NiMoO₄/NF demonstrated a high capacity and good rate capability in the Zn–Ni battery. The subsequent coating of the Co-based oxygen catalyst resulted in the Co-NiMoO₄/NF and enabled the battery to exhibit the advantages of both batteries.
