Herein, a hybrid electrolyte MgCl_(2)/AlCl_(3)/Mg(TFSI)_(2) (MACT) in dimethyl ether (DME) is developed and exhibits excellent electrochemical performance. The high ionic conductivity (6.82 mS cm~(–1)) and unique solvation structure of [Mg_(2)(μ-Cl)_(2)(DME)_(4)]~(2+) ...
(2)/DME-TFEB electrolyte could cycle stably for over 400 h with a small polarization voltage of~150 mV.Even with the presence of 800 ppm H_(2)O,the electrolyte with TFEB additive could still preserve its good electrochemical performance.The optimized electrolyte also enabled stab...
The Mg-Mg symmetrical cell with modified Mg electrode exhibits lower overpotential (~0.25聽V) and interfacial impedance than bare Mg electrode in 0.5聽M聽Mg(TFSI) 2 /DME electrolyte. The voltage hysteresis in the Mg-S and Mg-Mo 6 S 8 batteries with the modified Mg anode is greatly ...
The thermodynamics and reaction pathway of sulfur cathode in MgTFSI 2 -DME electrolyte, as well as the associated kinetics are thoroughly investigated. The results here reveal that sulfur undergoes a consecutive staging pathway in which the formation and chain-shortening of polysulfide occur at early...
