Abstract

Ni₃Fe oxide, with an average size of 3.5 ± 1.5 nm, was successfully deposited onto polyaniline (PANI) support through a solvothermal strategy followed by calcination. The catalyst–support interaction between Ni₃Fe oxide and PANI can enhance the Ni-O covalency via the interfacial Ni-N bond. Ni₃Fe oxide/PANI-assembled Zn-air batteries achieve superior cycling life for over 400 h at 10 mA cm⁻² and a low charge potential of around 1.95 V.
