Title (EN) ANODE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERY
(FR) MATÉRIAU ACTIF D'ANODE POUR BATTERIE SECONDAIRE AU LITHIUM
(KO) 리튬 이차 전지용 양극활물질
Abstract: front page image
(EN)The present invention relates to an anode active material for a lithium secondary battery, and more specifically the lithium secondary battery includes a first and a second concentration gradient part with nickel, manganese and cobalt each having a concentration presenting a gradient from the center toward the surface, and a first constant concentration part arranged between the first and the second concentration gradient part for making nickel, manganese and cobalt having a constant concentration.
(FR)La présente invention concerne un matériau actif d'anode pour une batterie secondaire au lithium, et plus particulièrement une batterie secondaire au lithium comprenant une première et une seconde partie à gradient de concentration contenant du nickel, du manganèse et du cobalt, dont la concentration présente respectivement un gradient du centre vers la surface, ainsi qu'une première partie à concentration constante, disposée entre la première et la deuxième partie à gradient de concentration, et produite de manière à présenter une concentration constante en nickel, manganèse et cobalt.
(KO)본 발명은 리튬 이차 전지용 양극활물질에 관한 것으로서, 더욱 상세하게는 중심으로부터 표면 방향으로 니켈, 망간 및 코발트의 농도가 구배를 나타내는 제 농도구배부, 제 2 농도구배부 및 상기 제 1 농도구배부와 제 2 농도구배부 사이에 니켈, 망간 및 코발트의 농도가 일정한 제 1 농도유지부를 포함하는 리튬 이차 전지용 양극활물질에 관한 것이다.
