Advanced Ether-Based Electrolytes for Lithium-ion Batteries

Lithium-ion batteries (LIBs) have emerged as vital elements of energy storage systems permeating every facet of modern living, particularly in portable electronic devices and electric vehicles. However, with the sustained economic and social development, new-generation LIBs with high energy density, wide operating temperature range, fast charge, and high safety are eagerly expected, while conventional ethylene carbonate (EC)-based carbonate electrolytes fail to satisfy corresponding requirements. Comparatively, ether-based electrolyte systems with fascinating properties have recently been revived in LIBs fields, and many advanced LIBs with exciting performances under ether-based electrolytes have been developed. This review provides an extensive overview of the latest breakthroughs concerning ether-based electrolytes applied in LIBs with intercalation cathodes. To systematically outline the progression of ether-based electrolytes, this review is categorized from the perspective of anodes as follows: i) graphite anode-based LIBs; ii) silicon anode-based LIBs; iii) lithium metal anode-based LIBs. Ether-based electrolytes with fascinating properties of high ionic conductivity, low viscosity, outstanding reduction stability, and wide temperature range have been revived in new-generation lithium batteries (LIBs). This review summarizes recent advances in ether-based electrolytes in LIBs with intercalation cathodes, which involve graphite anode-based, silicon anode-based, and lithium metal anode-based LIBs. Lastly, challenges and prospects of ether-based electrolytes are discussed. image
