Title (EN) ANODE ACTIVE MATERIAL FOR LITHIUM RECHARGEABLE BATTERY
(FR) MATÉRIAU ACTIF D'ANODE POUR BATTERIE RECHARGEABLE AU LITHIUM
(KO) 리튬 이차 전지용 양극활물질
Abstract: front page image
(EN)The present invention relates to an anode active material for a lithium rechargeable battery, and more specifically relates to an anode active material for a lithium rechargeable battery of a novel construction which comprises two core parts exhibiting gradients in nickel, manganese and cobalt concentrations in the core-to-surface direction, and in which the magnitudes of the nickel, manganese and cobalt concentration gradients in the two core parts is adjusted positively/negatively.
(FR)La présente invention concerne un matériau actif d'anode pour une batterie rechargeable au lithium, et plus particulièrement un matériau actif d'anode pour une batterie rechargeable au lithium qui présente une nouvelle structure comprenant deux parties coeur présentant des gradients de concentration en nickel, manganèse et cobalt du coeur vers la surface, les valeurs des gradients des concentrations en nickel, manganèse et cobalt des gradients dans deux parties coeur étant définies comme valeurs positives ou négatives.
(KO)본 발명은 리튬 이차 전지용 양극활물질에 관한 것으로서, 더욱 상세하게는 중심으로부터 표면 방향으로 니켈, 망간 및 코발트의 농도가 구배를 나타내는 2개의 코어부를 포함하고, 상기 2개의 코어부에서의 니켈, 망간 및 코발트의 농도 구배 크기가 양음으로 조절되는 새로운 구조의 리튬 이차 전지용 양극활물질에 관한 것이다.
