Zn-In alloy material with high hydrogen evolution overpotential was prepared on the cathodic current-collector surface of the alkaline Zn/MnO2 battery by chemical plating. The properties, effects on the battery performances and the composition of the Zn-In alloy material were studied by linear scanning voltammetry, X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), electrochemical impedance spectra (EIS) and altimetry. The results indicate that Zn-In alloy material could increase the hydrogen evolution overpotential of current-collector obviously and was capable of restricting hydrogen evolution effectively to improve the performances of batteries, which can reduce the cost and protect the environment well. Therefore, the Zn-In alloy materials have promising application in Ag-free battery industry, as the replacement of the conventional In coated copper current-collector
