Abstract: front page image
(EN) The present invention provides an anode composition for a lithium secondary battery, which comprises: a core; and a shell disposed on the surface of the core and having at least one active material layer and at least one non-active material layer alternately laminated thereon, wherein the at least one active material layer changes in volume upon reaction with lithium ions and the at least one non-active material layer is smaller in volume change rate than the at least one active material layer.
(FR) La présente invention concerne une composition d'anode destinée à une batterie secondaire au lithium, comprenant : un noyau ; et une enveloppe disposée sur la surface du noyau et présentant au moins une couche de matériau actif et au moins une couche de matériau non actif stratifiées en alternance sur ladite enveloppe, ladite couche de matériau actif changeant en volume par réaction avec des ions lithium, et ladite couche de matériau non actif étant plus faible en taux de changement de volume que ladite couche de matériau actif.
(KO) 본 발명은 코어 및 상기 코어의 표면 상에 배치되며, 리튬 이온과 반응하여 부피 변화가 발생하는 적어도 하나의 활물질층과, 상기 적어도 하나의 활물질층보다 부피 변화율이 작은 적어도 하나의 비활물질층이 교번 적층된 쉘을 구비하는, 리튬 이차 전지용 음극 조성물을 제공한다.
