Abstract
To provide a non-aqueous electrolyte solution for secondary batteries, by which a secondary battery having both high conductivity and stability free from thermal runaway may be obtained. A non-aqueous electrolyte solution for secondary batteries, which comprises a lithium salt (a1) represented by R1—CHF—SO2—N(Li)—SO2—CHF—R2 wherein in the formula (a1), each of R1 and R2 which are independent of each other, is a fluorinated C1-5 alkyl group which may contain an ethereal oxygen atom, or a fluorine atom, an inorganic lithium salt (a2), and a solvent, wherein the proportion of the lithium salt (a1) based on the total amount i.e. 100 mol % of the lithium salt (a1) and the inorganic lithium salt (a2) is from 5.0 to 20.0 mol %.
