Abstract
(EN)
Provided is a non-aqueous electrolyte secondary battery comprising: a positive electrode; a negative electrode; a separator disposed between the positive electrode and the negative electrode; and a non-aqueous electrolytic solution containing a lithium salt and a carboxylic acid, wherein the lithium salt includes lithium difluorophosphate, and the content of the carboxylic acid in the non-aqueous electrolytic solution is 5-900 ppm with respect to the mass of the non-aqueous electrolytic solution.
(FR)
L'invention concerne une batterie secondaire à électrolyte non aqueux comprenant : une électrode positive; une électrode négative; un séparateur disposé entre l'électrode positive et l'électrode négative; et une solution électrolytique non aqueuse contenant un sel de lithium et un acide carboxylique, le sel de lithium comprenant du difluorophosphate de lithium, et la teneur de l'acide carboxylique dans la solution électrolytique non aqueuse étant de 5-900 ppm par rapport à la masse de la solution électrolytique non aqueuse.
(JA)
正極、負極、正極と負極との間に介在するセパレータおよび非水電解液を有し、非水電解液は、リチウム塩と、カルボン酸とを含み、リチウム塩は、ジフルオロリン酸リチウムを含み、非水電解液に含まれるカルボン酸の含有量が、非水電解液の質量に対して5ppm以上、900ppm以下である、非水電解質二次電池。
