Title (EN) LITHIUM SECONDARY BATTERY EXHIBITING EXCELLENT PERFORMANCE
(FR) BATTERIE RECHARGEABLE AU LITHIUM PRÉSENTANT UNE EXCELLENTE PERFORMANCE
(KO) 성능이 우수한 리튬 이차전지
Abstract: front page image
(EN)The present invention provides a lithium secondary battery comprising an electrode assembly and an electrolyte, wherein the electrode assembly includes a cathode, an anode, and a separator disposed between the cathode and the anode. The lithium secondary battery of the present invention is characterized in that the anode includes lithium titanium oxide (LTO) as an anode active material, the cut-off voltage for charging ranges from 3.3 to 4 V, and the anode voltage when the voltage reaches the cut-off voltage is in the range of 0.75 to 1.545 V while the cathode voltage is less than 4.95 V.
(FR)La présente invention concerne une batterie rechargeable au lithium, comprenant un ensemble d'électrodes et un électrolyte, ledit ensemble d'électrodes comprenant une cathode, une anode et un séparateur disposé entre la cathode et l'anode. La batterie rechargeable au lithium selon l'invention est caractérisée en ce que l'anode comprend du titanate de lithium (LTO) en tant que matériau actif d'anode. Ladite batterie rechargeable au lithium est en outre caractérisée en ce que la tension de coupure pour la charge va de 3,3 à 4 V, et la tension anodique va de 0,75 à 1,545 V quand la tension de coupure est atteinte, tandis que la tension cathodique est inférieure à 4,95 V.
(KO)본 발명은 양극, 음극, 상기 양극과 상기 음극 사이에 배치되는 분리막으로 구성된 전극조립체 및 전해액을 포함하는 리튬 이차전지로서, 상기 음극이 음극 활물질로서 리튬 티타늄 산화물(Lithium Titanium Oxide: LTO)을 포함하고 있고, 상기 리튬 이차전지는 3.3 ~ 4V 범위의 충전 컷 오프 전압(cut-off voltage)을 가지며, 상기 컷 오프 전압에 도달시 음극의 전위는, 양극의 전위가 4.95V를 초과하지 않는 범위에서 0.75 ~ 1.545V인 것을 특징으로 하는 리튬 이차전지를 제공한다.
