In an attempt to realize an energy-sustainable society, considerable attention has been shifted towards the research and development of advanced post-lithium secondary batteries. An important avenue of research for post-lithium batteries is in electrolytes. Due to their remarkable electrochemical and physicochemical properties highly-concentrated electrolytes, termed “chelate or solvate ionic liquids” and formed by appropriate combinations of metal-salts and ethereal solvents, have attracted much attention for a variety of purposes, including as electrolytes for aluminum-based batteries. Herein, we present recent work that describes the behavior of potential solvate ionic liquids formed by dissolving Aluminum-Trifluoromethanesulfonate (Al-Trif) in Tetrahydrofuran (THF). Experimental techniques and density functional theory calculations were performed to study the electrochemical and spectroscopic features of the Al-Trif/THF binary mixtures.
