Tailoring anion-dominant solvation environment by steric-hindrance effect and competitive coordination for fast charging and stable cycling lithium metal batteries

Through the steric-hindrance effect of cyclohexyl methyl ether and the competitive coordination between the co-solvent and solvent molecules, the Li + solvation environment is reshaped, and the long cycle and fast charging of lithium metal batteries are realized. The properties of electrolytes are critical for fast-charging and stable-cycling applications in lithium metal batteries (LMBs). However, the slow kinetics of Li + transport and desolvation in commercial carbonate electrolytes, coupled with the formation of unstable solid electrolyte interphases (SEI), exacerbate the degradation of LMB performance at high current densities. Herein, we propose a versatile electrolyte design strategy that incorporates…
