Abstract
A non-aqueous electrolytic solution capable of suppressing reduction in capacity, cycle characteristics, and/or rate characteristics even when used under high voltage conditions after being stored under high temperature conditions (e.g., 60° C. or higher); and a lithium ion secondary battery using these non-aqueous electrolytic solutions are provided. The non-aqueous electrolytic solution of the present invention comprise an anion represented by the following general formula (1), a lithium cation, and a compound represented by the following general formula (2A) and/or an acid anhydride having an aromatic ring and at least one structure represented by —C(═O)—O—C(═O)— in a molecule, wherein a concentration of the anion represented by the general formula (1) is 0.1 mol/L or more.
