Rechargeable high energy density Li batteries require an efficient Li electrode. Earlier work with propylene carbonate (PC), methyl acetate (MA), and tetrahydrofuran (THF)-based electrolytes yielded poor Li electrode cycling efficiencies due to the electrolyte reduction by Li. We find 2-methyltetrahydrofuran (2-Me-THF)/LiAsF6 media to be remarkably stable toward Li; this stability results in cycling efficiencies which approach 98%. The ability of 2-Me-THF in particular, and alpha-methylated THFs in general, to resist reduction by Li is thought to be based on the position of its lowest unfilled molecular orbital (LUMO) relative to that of THF.
