Patent

CA 2696196

A lithium ion secondary battery (100) has a property of securing a flat charge-discharge capacity range (FC) in which fluctuation of terminal voltage is 0.2 V or lower in both the cases where the battery is charged and discharged with electric current having a current value of 1 C over a capacity range of 50% or more of the electric capacity range having a theoretical electric capacity as an upper limit.

L'invention concerne une batterie secondaire lithium-ion (100) présentant une propriété permettant d'assurer une plage de capacité de charge-décharge plate (FC) dans laquelle la fluctuation de tension aux bornes est de 0,2 V ou moins dans les deux cas où la batterie est chargée ou déchargée avec un courant électrique ayant une valeur d'intensité de 1 C sur une plage de capacité de 50 % ou plus de la plage de capacité électrique ayant une capacité électrique théorique en tant que limite supérieure.
