Zusammenfassung: | The present invention relates to an anode for a lithium secondary battery, a manufacturing method therefor, and a lithium secondary battery comprising same. More specifically, the anode has, between a plurality of lithium thin films, salt-coated layers comprising a lithium salt and an additive, so that, during operation of a battery, the lithium salt and additive of a consumed electrolyte can be replenished while the salt-coated layers dissolve, and thus the lifespan characteristics of the battery can be improved while high cooling efficiency is maintained.
La présente invention concerne une anode pour une batterie secondaire au lithium, son procédé de fabrication et une batterie secondaire au lithium la comprenant. Plus particulièrement, l'anode a, entre une pluralité de films minces de lithium, des couches revêtues de sel comprenant un sel de lithium et un additif, de sorte que, pendant le fonctionnement d'une batterie, le sel de lithium et l'additif d'un électrolyte consommé peuvent être remplis tandis que les couches revêtues de sel se dissolvent, et ainsi les caractéristiques de durée de vie de la batterie peuvent être améliorées tout en maintenant un rendement de refroidissement élevé.
본 발명은 리튬 이차전지용 음극, 이의 제조방법 및 이를 포함하는 리튬 이차전지에 관한 것이다. 보다 상세하게는, 상기 음극은 복수 개의 리튬 박막 사이에 리튬염 및 첨가제를 포함하는 염 코팅층이 형성되어 있어, 전지 구동 시 상기 염 코팅층이 용해되면서, 소모되는 전해질의 리튬염 및 첨가제를 보충해 수 있으므로, 높은 쿨링 효율을 유지하면서 전지의 수명 특성을 향상시킬 수 있다. |
