Nonaqueous electrolyte and nonaqueous electrolyte secondary battery

   
   

Disclosed is a nonaqueous electrolyte comprising a nonaqueous solvent which contains ethylene carbonate (EC), propylene carbonate (PC), .gamma.-butyrolactone (BL), and a fourth component, which is a solvent other than the EC, PC and BL, and the mixing ratio x (% by volume) of EC based on the total amount of the nonaqueous solvent falls within a range of between 15 and 50, the mixing ratio y (% by volume) of PC based on the total amount of the nonaqueous solvent falls within a range of between 2 and 35, the mixing ratio z (% by volume) of BL based on the total amount of the nonaqueous solvent falls within a range of between 30 and 85, and the mixing ratio p (% by volume) of the fourth component based on the total amount of the nonaqueous solvent is larger than 0 and is not larger than 5.

Révélé est un électrolyte non aqueux comportant un dissolvant non aqueux que qui contient le carbonate d'éthylène (la EC), le carbonate de propylène (PC), la gamma.-butyrolactone (BL), et un quatrième composant, qui est un dissolvant autre que la EC, PC et BL, et le rapport de mélange X (% par le volume) de la EC basé sur le montant total des chutes non aqueuses de dissolvant dans une marge de entre 15 et 50, le rapport de mélange y (% par le volume) du PC basé sur le montant total des chutes non aqueuses de dissolvant dans une marge de entre 2 et 35, le rapport de mélange z (% par le volume) du BL basé sur le montant total des chutes non aqueuses de dissolvant dans une marge de entre 30 et 85, et le rapport de mélange p (% par le volume) du quatrième composant basé sur le montant total du dissolvant non aqueux est plus grand que 0 et n'est pas plus grand que 5.
