Cyclic Voltammetry Measurements of Nitrogen-Containing Electrolytes
(A) Cyclic voltammograms and linear sweep voltammetry (inset) of 0.25 M MACC 2:1 solution in DME. The working electrode is Pt, while the counter and reference electrodes are Mg metal. Measurements were obtained at 25 mV s−1 and ambient conditions. Reprinted with permission from Doe et al.,35 copyright 2014 Royal Society of Chemistry.
(B–D) Typical cyclic voltammograms with Pt electrodes of 0.5 M THF solutions are shown for different ratios of Mg(HMDS)2 and MgCl2, respectively: (B) 2:1, (C) 1:2, and (D) 1:4. The scan rate was 100 mV/s with Pt working electrode and Mg ribbons as both reference and counter electrodes. Rreprinted with permission from Liao et al.,14 copyright 2012 Royal Society of Chemistry.

(A) Typical cyclic voltammetry (CV) of Pt working electrodes (WE) in (A) MgTFSI2 0.5 M in DME solution, scanned at 25 mV/s. The inset shows a CV of a Pt electrode in MgTFSI2 0.5 M solution in diglyme.
(B) MgTFSI2 0.25 M with MgCl2 0.5 M in DME, scanned at 25 mV/s. Mg foils served as reference and counter electrodes (RE and CE). Addition of MgCl2 significantly reduces the overpotential for both deposition and dissolution processes.
(C) Selected CV cycles during the conditioning procedure of MgTFSI2 0.25 M with MgCl2 0.5 M in DME solution, scanned at 1 mV/s. Pt served as WE and Mg as both RE and CE.
(D) Typical CV of Pt WE in conditioned MgTFSI2 0.25 M + MgCl2 0.5 M DME solution, scanned at 25 mV/s, with Mg foils as both RE and CE. Reprinted with permission from Shterenberg et al.,38 copyright 2015.

Impact of Artificial SEI on the Overall Electrochemical Performance
(A and B) Voltage responses of symmetric Mg cells under repeated polarization with and without artificial interphase in different electrolyte systems at a current density of 0.01 mA cm−2 showing reversible Mg deposition/stripping in (A) APC electrolyte, where each deposition/stripping cycle lasts for 1 hr, and (B) 0.5 M Mg(TFSI)2/PC electrolyte, where each deposition/stripping cycle lasts 30 min. The cell made with pristine Mg electrodes shows huge overpotential at the beginning and fails after 135 cycles, whereas the cell made with the Mg2+-conducting interphase-protected Mg electrodes performs prolonged cycles in carbonate-based electrolytes. The reversibility is conspicuous in the latter, as proven over 1,000 cycles.
(C) Voltage hysteresis versus cycle numbers for symmetric Mg electrodes with 0.5 M Mg(TFSI)2/PC electrolyte. Lower voltage hysteresis is observed for interphase-protected Mg electrode, where the artificial interphase prevents reductive decomposition of PC.
