摘要/Abstract

摘要： 制备了全苯基有机铝镁盐(PhMgCl)2-AlCl3，研究以3种不同混合醚，即dimethoxyethane (DME)+THF、Diglyme (DG)+THF和Tetraglyme (TG)+THF作溶剂对全苯基有机铝镁盐在不同金属电极上的电化学性能的影响. 结果表明，和(PhMgCl)2-AlCl3/THF体系相比，(PhMgCl)2-AlCl3/DG+THF(3:2)仍具有较高的离子电导率（1.605×10-3 S?cm-1）、良好的可逆沉积镁特性及阳极抗氧化性能（电化学窗口大于2.8 V）. 且该DG+THF混合溶剂还可大幅降低电解液的饱和蒸汽压（由23.46 kPa降低到9.41 kPa），减少了电池使用过程电解液的挥发，从而提高了可充镁电池的安全性能. 比较Pt、Ni、Cu和Al等不同金属基质电极，发现Pt的电化学性能最好，而Al最差.

Abstract: The (PhMgCl)2-AlCl3 salts were prepared and the electrochemical properties of (PhMgCl)2-AlCl3 electrolytes containing dimethoxyethane(DME)+THF, Diglyme(DG)+THF and Tetraglyme(TG)+THF solvents with different proportions on various metal electrodes were studied. Compared with (PhMgCl)2-AlCl3/THF, the (PhMgCl)2-AlCl3/DG+THF(3:2) solvents showed high ionic conductivity of 1.605×10-3 S?cm-1, good reversible Mg deposition behavior and anodic anti-oxidation performance with an electrochemical window wider than 2.8 V. In addition, the DG+THF mixed solvent could greatly lower the saturated vapor pressure by reducing from 23.46 kPa to 9.41 kPa, which suppresses volatilization of the electrolyte and improves the overall safety of rechargeable battery. Among Pt, Ni, Cu and Al electrodes, Pt offers the best electrochemical properties, while Al the worst.
