Abstract
A non-aqueous electrolyte solution for a lithium secondary battery includes a lithium salt and an organic solvent and further includes a solvent having a fluoro group and a specific siloxane compound. A lithium secondary battery having the above non-aqueous electrolyte solution exhibits greatly improved capacity recovery characteristics after high temperature storage and also reduces side effects such as swelling.
