Zusammenfassung:Compounds suitable for use in lithium-ion battery electrolytes are disclosed. An example of a suitable compound is lithium difluoro(bisoxalato) phosphate. A lithium-ion battery electrolyte includes a lithium salt composition and an electrolyte compound composition. In some embodiments, the lithium salt composition comprises one or more of the suitable compounds, a concentration of the suitable compounds in the lithium-ion battery electrolyte being in a range of about 0.1 mol. % to about 20 mol. %. In some implementations, the lithium salt composition may also comprise LiPF6. Lithium-ion batteries employing such electrolytes are also disclosed.
