Original Abstract

The study is focused on electrolytes for magnesium batteries. In contrast to electrolytes published in recent scientific articles, which were mostly prepared from either hazardous or expensive substances, the electrolytes in this work were composed of affordable solvents and chemicals, which can be handled at normal laboratory conditions. Specifically, solutions of dimethylsulfoxide and tetrahydrofurane with magnesium chloride, nitrilotriacetic acid, aluminium chloride, and disodium ethylenediaminetetraacetic acid, were examined. The ability of electrolyte to oxidize and deposit magnesium was characterized using cyclic voltammetry. More information about the kinetics of electrochemical reactions in terms of polarization resistance was obtained by electrochemical impedance spectroscopy. EIS was also used to reveal formation of oxide layer on electrode and its homogeneity. Magnesium electrodes from electrochemical measurements were finally examined by scanning electron microscopy with energy-dispersive X-ray spectroscopy. Based on the SEM pictures and EDS data, the effect of humidity and atmospheric oxygen on magnesium electrode corrosion during electrochemical cycling was discussed.
