Abstract:
(EN) The present invention relates to a negative electrode active material having excellent output characteristics, with low gas generation, and an electrode containing the negative electrode active material. The negative electrode active material comprises MO-LTO composite particles (metal oxide (MO)-lithium titanium oxide (LTO) composite particles), wherein the composite particles have the morphology of secondary particles into which primary particles aggregate, the primary particles having a core-shell structure in which a core is at least partially or entirely covered with a shell, the core being a primary particle of lithium titanium oxide (LTO), the shell comprising a metal oxide.
(FR) L'invention concerne un matériau actif d'électrode négative présentant d'excellentes caractéristiques de rendement avec faible production de gaz, et une électrode contenant le matériau actif d'électrode négative. Le matériau actif d'électrode négative comprend des particules composites MO-LTO (particules composites d'oxyde métallique (MO) et d'oxyde de lithium-titane (LTO)). Les particules composites présentent la morphologie de particules secondaires dans lesquelles des particules primaires sont agrégées. Les particules primaires présentent une structure noyau-enveloppe dans laquelle un noyau est au moins partiellement ou intégralement recouvert d'une enveloppe, le noyau étant une particule primaire d'oxyde de lithium-titane (LTO), l'enveloppe comprenant un oxyde métallique.
(KO) 본원 발명은 출력 특성이 우수하고 가스 발생이 적은 음극 활물질 및 상기 음극 활물질을 포함하는 전극에 대한 것이다. 상기 음극 활물질은 MO-LTO 복합입자(금속 산화물(Metal oxide; MO)-리튬 티타늄 옥사이드(Lithium titanium oxide; LTO) 복합 입자)를 포함하는 것으로서, 상기 복합 입자는 1차 입자가 응집되어 형성된 2차 입자의 형태를 갖고, 상기 1차 입자는 코어(core) 및 상기 코어의 표면 전부 또는 적어도 일부를 피복하는 쉘(shell)을 포함하는 코어-쉘 구조를 갖고, 상기 코어는 리튬 티타늄 옥사이드(Lithium titanium oxide; LTO)의 1차 입자이고, 상기 쉘은 금속 산화물을 포함한다.
