Abstract Ionic liquids are considered as a potential electrolyte for rechargeable zinc–air battery due to non-volatility, high ionic conductivity, and so on. Electrochemical measurements are conducted to investigate the redox behavior of zinc electrode in 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide ([BMPyr] [NTf 2 ]) ionic liquid and the effect of water in the ionic liquid is also studied. Cyclic voltammetry of zinc electrode in [BMPyr] [NTf 2 ] shows a reversible redox peak, and the presence of water gives significant effects particularly on the cathodic current of zinc electrode. Different surface reaction mechanism on zinc electrode depending on the presence of water in ionic liquid is suggested.
