Magnesium based batteries have the potential to provide an alternative storage medium with several potential advantages over the current leading technologies, including higher specific energy and safer manufacturing and handling capabilities. Ionic liquids (ILs) are a promising type of medium for Mg batteries given their excellent chemical stability, low volatility and wide electrochemical windows. We report conditions under which chemically reversible redox behavior for Mg is observed as evidenced by cyclic voltammograms.  Clear evidence for additional cathodic and subsequent anodic processes is observed upon addition of Mg2+ salts to pyrrolidinium based ionic liquids. Through the use of other techniques like Raman spectroscopy, X-ray diffraction and scanning electron microscopy we are able to correlate electron transfer kinetics with solvent environment and solid deposit characteristics, respectively.
