Electrodeposition of manganese (Mn) in butylmethylpyrrolidinium bis(trifluoromethylsulfony)imide (BMP–NTf 2) ionic liquid is demonstrated in this study. Crystal structures and surface morphologies of the Mn films deposited at various potentials (from −1.8 V to −2.2 V) and temperatures (from 50 °C to...
