文摘

In this paper we reported for the first time the electrochemical behavior of thiolate-based solutions (RSMgCl)_n-AlCl₃/THF (R = 4-methyl-benzene, p-isopropylbenzene, 4-methoxybenzene, n = 1-2), formed from the reaction between RSMgCl and AlCl₃ in THF, as electrolyte for rechargeable magnesium batteries. The solutions were characterized in term of conductivity, anodic stability, and reversibility of magnesium deposition and dissolution. Furthermore, the compatibility of the solutions with Mo₆S₈ cathode material was verified. Simple preparation, high cycling reversibility, moderate anodic stability, air insensitive character and the reversible electrochemical process of Mg intercalation into Mo₆S₈ cathode indicate the feasible application as the electrolyte for rechargeable magnesium batteries.
