Abstract

The potential increase in cost of lithium-ion batteries owing to the limited supply of lithium has prompted investigations into alternative and complementary rechargeable batteries that use post-lithium charge carriers with higher elemental abundance. However, achieving highly reversible post-lithium metal anodes with sufficient kinetics remains challenging. The addition of co-solvents to conventional electrolytes is emerging as an important strategy to resolve these issues. In this Perspective, we discuss the progress of the co-solvent strategy for sodium, potassium, magnesium, calcium, zinc and aluminium post-lithium metal batteries. The coordination ability of co-solvents with post-lithium charge carriers is presented as a useful guide for selecting co-solvents for the respective battery electrolytes, owing to its correlation with several influential factors that affect the electrochemical performance of the metal anodes, such as solvation structure, de-solvation process and solid electrolyte interphase formation. Additionally, a discussion is provided on the importance of unravelling the effects beyond the solvation sheath of cationic charge carriers and for the development of sustainable electrolytes.

可充电后锂金属电池的共溶剂策略。
由于锂供应有限,锂离子电池的成本可能会增加,这促使人们研究使用元素丰度更高的后锂电荷载体的替代和互补可充电电池。然而,获得具有足够动力学的高可逆后锂金属阳极仍然具有挑战性。在传统电解质中添加共溶剂是解决这些问题的重要策略。本文主要讨论了钠、钾、镁、钙、锌、铝后锂金属电池的共溶剂策略的研究进展。共溶剂与后锂载流子的配位能力与影响金属阳极电化学性能的几个因素(如溶剂化结构、脱溶剂化过程和固体电解质间相形成)相关,可以作为选择电池电解质共溶剂的有用指南。此外,还讨论了揭示阳离子载流子溶剂化鞘之外的影响以及开发可持续电解质的重要性。
