Summary:Provided is a nonaqueous electrolyte solution which is used as an electrolyte solution for a nonaqueous secondary battery and capable of improving the discharge rate characteristics of the battery. The nonaqueous electrolyte solution contains a nonaqueous solvent and a BF3-cyclic ether complex. The BF3-cyclic ether complex is contained in an amount of more than 0 part by mass but less than 1 part by mass relative to 100 parts by mass of the total of the other components of the electrolyte solution. Preferable examples of the BF3-cyclic ether complex may include a BF3-tetrahydropyran complex and a BF3-dioxane complex. L'invention concerne une solution d'électrolyte non aqueuse qui est utilisée comme solution d'électrolyte pour un accumulateur non aqueux et qui permet d'améliorer les caractéristiques de taux de décharge de la batterie. La solution d'électrolyte non aqueuse contient un solvant non aqueux et un complexe d'éther cyclique de BF3. Le complexe d'éther cyclique de BF3 est contenu dans une quantité supérieure à 0 et inférieure à 1 partie en masse par rapport à 100 parties en masse du total des autres composants de la solution d'électrolyte. Des exemples préférables du complexe d'éther cyclique en BF3 peuvent comprendre un complexe BF3-tétrahydropyranne et un complexe BF3-dioxane.
