Title (EN) POSITIVE ELECTRODE ACTIVE MATERIAL FOR SODIUM SECONDARY BATTERY, AND METHOD FOR PREPARING SAME
(FR) MATÉRIAU ACTIF D'ÉLECTRODE POSITIVE POUR UNE BATTERIE RECHARGEABLE AU SODIUM, ET SON PROCÉDÉ DE PRÉPARATION
(KO) 나트륨 이차전지용 양극활물질 및 이의 제조 방법
Abstract: front page image
(EN)The present invention relates to a positive electrode active material for a sodium secondary battery, and a method for preparing the same. The positive electrode active material for the sodium secondary battery according to the present invention is structurally more stable by replacing a part of the transition metal with Li, and accordingly, the thermal stability and life characteristics of the sodium battery comprising the positive electrode active material are greatly improved.
(FR)La présente invention se rapporte à un matériau actif d'électrode positive pour une batterie rechargeable au lithium, et à son procédé de préparation. Le matériau actif d'électrode positive pour la batterie rechargeable au sodium selon la présente invention est structurellement plus stable grâce au remplacement d'une partie du métal de transition par du lithium (Li) et, en conséquence, les caractéristiques de stabilité thermique et de durée de vie de la batterie au sodium comprenant le matériau actif d'électrode positive sont fortement améliorées.
(KO)본 발명은 나트륨 이차전지용 양극활물질 및 이의 제조 방법에 관한 것이다. 본 발명에 의한 나트륨 이차전지용 양극활물질은 전이금속을 일부 Li 으로 치환함으로써 구조적으로 더 안정하고 그에 따라 상기 양극활물질을 포함하는 나트륨 전지의 열적 안정성 및 수명 특성이 크게 개선된다.
