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.
期刊介绍:
Nature Reviews Chemistry is an online-only journal that publishes Reviews, Perspectives, and Comments on various disciplines within chemistry. The Reviews aim to offer balanced and objective analyses of selected topics, providing clear descriptions of relevant scientific literature. The content is designed to be accessible to recent graduates in any chemistry-related discipline while also offering insights for principal investigators and industry-based research scientists. Additionally, Reviews should provide the authors' perspectives on future directions and opinions regarding the major challenges faced by researchers in the field.
