摘要
自从Muldoon课题组在2011年首次报道以[Mg_(2)(μ-Cl)_(3)(THF)_(6)]^(+)为阳离子电化学活性中心的非亲核有机铝镁盐用于镁硫电池以来,非亲核镁电解液便引起了人们的广泛关注.本文综述了非亲核镁电解质的合成、阳离子结构及其镁硫电池电解液电化学性能的研究进展.最后对非亲核镁硫电池电解液未来的发展方向进行了前瞻性的探讨,指出要推动镁硫电池的产业化,除了要开发高性能、低成本、结构简单的非亲核电解质材料以外,深入研究电解质盐及电解液组分与正/负电极材料最优匹配机制也至关重要.
Non-nucleophilic magnesium electrolyte has attracted significant attention since the first non-nucleophilic organic aluminum magnesium salt with [Mg_(2)(μ-Cl)_(3)(THF)_(6)]^(+) as the cation of electrochemical active center for magnesium/sulfur(Mg/S)cells was reported by Muldoon group in 2011.In this work,we reviewed the synthesis,cation structure and electro chemical performance of non-nucleophilic magnesium electrolyte for Mg/S battery.The future research directions of non-nucleophilic Mg/S battery electrolyte are discussed.It is pointed out that in order to promote the industrialization of Mg/S battery,in addition to the development of non-nucleophilic electrolyte materials with high performance,low cost and simple structure,further mechanistic understanding for optimization of electrolyte composition and for better matching be tween the electrolyte with positive or negative electrode materials is also very important.
