Title
(EN) HIGH-CURRENT PROCESSING FOR LITHIUM ION BATTERY HAVING METAL-BASED NEGATIVE ELECTRODE

Abstract
(EN) The present invention relates to a lithium ion battery and a production method therefor, and more specifically, to a method for improving low-temperature capabilities of a lithium ion battery, and to a lithium ion battery having improved rate capacity characteristics. The production method for this lithium ion battery comprises: a step of preparing a unit cell containing a positive electrode, a separator, an electrolyte, and a metal-based negative electrode having an alloyed particle, and then applying a high C-rate discharge current to the unit cell; and a step of stopping the supply of the high C-rate discharge current, then, applying a high C-rate charging current to the unit cell, to charge the unit cell to a high charging level no lower than 90% of the charging level maximum value in the unit cell. Then, the applied high C-rate discharge current (CHD) is higher than a C-rate operating current (Co) passing through the metal-based negative electrode during the use of the lithium ion battery.
(FR) La présente invention concerne une batterie lithium-ion et son procédé de fabrication, et, plus précisément, un procédé d'amélioration des capacités à basse température d'une batterie lithium-ion et une batterie lithium-ion ayant des caractéristiques de capacité de régime améliorées. Le procédé de fabrication de cette batterie lithium-ion comprend les étapes suivantes : la préparation d'une cellule unitaire contenant une électrode positive, un séparateur, un électrolyte et une électrode négative à base de métal ayant des particules alliées, puis l'application d'un courant de décharge à régime C élevé à la cellule unitaire; l'arrêt de la fourniture du courant de décharge à régime C élevé, puis l'application d'un courant de charge à régime C élevé à la cellule unitaire afin de charger celle-ci à un niveau de charge élevé, supérieur ou égal à 90 % de la valeur maximale du niveau de charge dans la cellule unitaire. Le courant de décharge à régime C élevé (CHD) appliqué est donc supérieur à un courant de fonctionnement à régime C (Co) traversant l'électrode négative à base de métal pendant l'utilisation de la batterie lithium-ion.
