Abstract
(EN)
Provided is a nonaqueous electrolytic solution that improves safety of batteries. This nonaqueous electrolytic solution has a volatilization temperature not less than 80°C, and log(O/Li), which is the logarithm of the ratio of the amount of oxygen contained in the nonaqueous electrolytic solution with respect to the amount of lithium contained in the nonaqueous electrolytic solution, is 0.87-2.05.
(FR)
L'invention concerne une solution électrolytique non aqueuse qui améliore la sécurité des batteries. Cette solution électrolytique non aqueuse a une température de volatilisation supérieure ou égale à 80 °C, et un log(O/Li), qui est le logarithme du rapport de la quantité d'oxygène contenu dans la solution électrolytique non aqueuse par rapport à la quantité de lithium contenu dans la solution électrolytique non aqueuse, est de 0,87 à 2,05.
(JA)
電池の安全性を向上させる非水電解液を提供する。揮発温度が80℃以上の非水電解液であり、非水電解液に含まれるリチウム量に対する非水電解液に含まれる酸素量の比の対数であるlog(O/Li)が0.87~2.05である非水電解液。
