Abstract:
(EN) The present invention relates to a method for producing a lithium manganese oxide-based positive electrode active material for a pseudocapacitor and for a lithium ion battery and, more specifically, can produce a lithium manganese oxide-based positive electrode active material having a large surface area despite the small size and an excellent specific capacitance, by performing a heat treatment process in stages under optimized conditions by synthesizing manganese oxide nanoparticles and then mixing same with a lithium salt.
(FR) La présente invention concerne un procédé de production d'un matériau actif d'électrode positive à base d'oxyde de lithium-manganèse pour un pseudo-condensateur et pour une batterie au lithium-ion et, plus spécifiquement, un procédé qui peut produire un matériau actif d'électrode positive à base d'oxyde de lithium-manganèse ayant une grande surface en dépit de la petite taille et une excellente capacité spécifique, par réalisation d'un processus de traitement thermique dans des étapes effectuées dans des conditions optimisées par synthèse de nanoparticules d'oxyde de manganèse, puis par mélange de celles-ci avec un sel de lithium.
(KO) 본 발명에서는 수도커패시터용 및 리튬이온배터리용 리튬망간산화물계 양극활물질의 제조 방법에 관한 것으로서, 보다 상세하게는 망간산화물 나노입자를 합성한 후에 리튬염과 혼합하여최적화된 조건 하에서 단계적으로 열처리 공정을 수행함으로써, 적은 크기로 높은 표면적을 갖는 비정전용량이 우수한 리튬망간산화물계 양극활물질을 제조할 수 있다.
