2-methyltetrahydrofuran-lithium hexafluoroarsenate: a superior electrolyte for the secondary lithium electrode
Journal Article
·
· Science; (United States)
Rechargeable, high-energy-density lithium batteries require an efficient lithium electrode. Earlier work with electrolytes based on propylene carbonate, methyl acetate, and tetrahydrofuran yielded poor lithium electrode cycling efficiencies because of electrolyte reduction by lithium. Solutions of lithium hexafluoroarsenate in 2-methyltetrahydrofuran are found to be remarkably stable toward lithium and result in cycling efficiencies that approach 98%. The ability of 2-methyltetrahydrofuran to resist reduction by lithium is thought to be based on the position of its lowest unfilled molecular orbital relative to that of tetrahydrofuran. 2 figures.
