Abstract: front page image
(EN)The present invention relates to an electrode for a lithium secondary battery with high energy density, and to a high energy density secondary battery using same. The present invention relates to an electrode for a lithium secondary battery, wherein a negative electrode contains a material to be made into a lithium alloy, and a positive electrode comprises a transition metal oxide which reversibly occludes and releases lithium. The secondary battery of the present invention has a total reversible lithium storage capacity larger than the lithium capacity releasable from the positive electrode. Either one of or both the positive electrode and the negative electrode has a surface on which metal lithium is deposited. The present invention also relates to a method for manufacturing the electrode, and to a lithium secondary battery comprising the electrode. The lithium secondary battery of the present invention has no metal lithium remaining after activation, thereby achieving improved safety and capacity per unit weight.
(FR)La présente invention concerne une électrode pour une batterie secondaire au lithium à haute énergie volumique, et une batterie secondaire à haute énergie volumique utilisant ladite électrode. La présente invention concerne une électrode pour une batterie secondaire au lithium, une électrode négative contenant un matériau à combiner dans un alliage de lithium, et une électrode positive comprenant un oxyde de métal de transition qui bloque et libère de manière réversible le lithium. La batterie secondaire de la présente invention a une capacité de stockage de lithium totalement réversible supérieure à la capacité de lithium libérable par l'électrode positive. L'une des deux ou bien les deux électrodes positive et négative a/ont une surface sur laquelle le métal lithium est déposé. La présente invention concerne également un procédé de production de l'électrode, et une batterie secondaire au lithium comprenant l'électrode. La batterie secondaire au lithium de la présente invention est dépourvue de métal de lithium restant après activation, ce qui permet d'accomplir une sécurité améliorée et une capacité par unité de poids.
(KO)본 발명은 고에너지 밀도의 리튬이차전지용 전극 및 이를 적용한 고에너지 밀도 이차전지에 대한 것으로, 음극에는 리튬 합금이 가능한 소재를 함유하고, 양극은 가역적인 리튬 흡장 방출이 가능한 전이 금속 산화물로서, 전체 가역적인 리튬 저장능력이 양극에서 방출될 수 있는 리튬 용량보다 큰 것을 특징으로 하며, 상기 음극 및 양극 중 하나 또는 두 개의 전극 표면에 금속 리튬이 도포된 리튬이차전지용 전극 및 그 제조방법, 및 이를 포함하는 리튬이차전지에 대한 것이다. 본 발명의 리튬이차전지는 활성화 이후 금속 리튬이 잔존하지 않아 안전성이 우수하며, 단위 무게당 용량이 우수하다.
