Abstract:
(EN) According to the present invention, a lithium ion secondary battery, which is provided with a positive electrode that contains a positive electrode active material containing a lithium nickel composite oxide, uses a cyclic sulfonic acid ester (a1) that has at least two sulfonyl groups in each molecule and a compound (a2) that has only one sulfonyl group in each molecule, while having a highest occupied molecular orbital energy level of -11.2 eV or less as calculated by PM3 method for the electrolyte. In addition, a coating film containing sulfur atoms is formed on at least a part of the surface of the positive electrode active material by charging the above-described battery.
(FR) Selon la présente invention, une batterie secondaire au lithium-ion, qui comprend une électrode positive qui contient un matériau actif d'électrode positive contenant un oxyde composite de lithium-nickel, utilise un ester d'acide sulfonique cyclique (a1) qui a au moins deux groupes sulfonyle dans chaque molécule et un composé (a2) qui n'a qu'un groupe sulfonyle dans chaque molécule, tout en ayant un niveau d'énergie orbitale moléculaire occupée la plus haute inférieur ou égal à -11,2 eV, tel que calculé par le procédé PM3 pour l'électrolyte. De plus, un film de revêtement contenant des atomes de soufre est formé sur au moins une partie de la surface du matériau actif d'électrode positive par chargement de la batterie décrite ci-dessus.
