Abstract
(EN) The objectives of the present invention are to suppress the elution of manganese from a cathode active material during storage at high temperature of a lithium ion secondary battery using a manganese oxide as the cathode active material and to suppress the drop in capacity, the increase in resistance, and the shortening of the service life of the lithium ion secondary battery. The lithium ion secondary battery of the present invention has a cathode having at least manganese oxide as the cathode active material, an anode capable of storing and discharging lithium, and an electrolytic solution composed of a nonaqueous solvent containing lithium salt. If the weight of the electrolytic solution is A (g), and the weight of the manganese oxide is B (g), then the value of C = A/B is from 0.96 to 8.50.
(FR) L'objet de la présente invention est de supprimer l'élution de manganèse d'un matériau actif de cathode pendant un stockage à une température élevée d'une batterie secondaire au lithium-ion au moyen d'un oxyde de manganèse comme matériau actif de cathode, et de supprimer la baisse de capacité, l'augmentation de la résistance et le raccourcissement de la durée de vie de la batterie secondaire au lithium-ion. La batterie secondaire au lithium-ion de la présente invention présente une cathode possédant au moins de l'oxyde de manganèse comme matériau actif de cathode, une anode capable de stocker et d'évacuer du lithium et une solution électrolytique composée d'un solvant non aqueux contenant du sel de lithium. Si le poids de la solution électrolytique est A (g) et si le poids de l'oxyde de manganèse est B (g), la valeur de C = A/B se situe alors dans la plage de 0,96 à 8,50.
