Mg batteries are a potential beyond Li-ion technol. but currently suffer from poor cycling performance, partly due to the interphase formed when Mg electrodes react with electrolytes. The use of Mg bis(trifluoromethanesulfonyl)imide (Mg(TFSI)2) electrolytes would enable high-voltage intercalation cathodes, but many reports identify poor Mg plating/stripping in the electrolyte solution due to a passivating interphase. Here, the authors have assessed the Mg plating/stripping mechanism at bulk Mg electrodes in a Mg(TFSI)2-based electrolyte by cyclic voltammetry, ex situ FTIR spectroscopy, and electron microscopy and compared this to the cycling of a Grignard-based electrolyte. The authors’ studies indicate a nontypical cycling mechanism at Mg surfaces in Mg(TFSI)2-based electrolytes that occurs through Mg deposits rather than the bulk electrode. FTIR spectroscopy demonstrates an evolution in the interphase chem. during conditioning (repeated cycling) and that this is a critical step for stable cycling in the Mg(TFSI)2-tetraglyme (4G) electrolyte. The fully conditioned electrode in Mg(TFSI)2-4G is able to cycle with an overpotential of <0.25 V without addnl. additives such as Cl- or BH4-.
