Abstract:
(EN) The present invention provides a positive electrode active material for a secondary battery, a positive electrode, for a secondary battery, comprising same, and a secondary battery. The positive electrode active material comprises: a core which comprises lithium composite metal oxide; and a surface treatment layer which is disposed on the surface of the core, wherein the surface treatment layer comprises a porous coordination polymer having central metal ions coordinate-bonded to organic ligands. Therefore, the present invention enables high electrode density during preparation of the electrode, thereby greatly enhancing battery characteristics.
(FR) La présente invention concerne une matière active d'électrode positive pour pile rechargeable, une électrode positive pour pile rechargeable la comprenant, et une pile rechargeable. La matière active d'électrode positive comprend : un cœur qui comprend un oxyde métallique composite de lithium ; et une couche de traitement de surface qui est disposée sur la surface du cœur, la couche de traitement de surface comprenant un polymère de coordination poreux contenant des ions métalliques centraux liés par liaison de coordination à des ligands organiques. Par conséquent, la présente invention permet une haute densité d'électrode pendant la préparation de l'électrode, ce qui permet d'améliorer considérablement les caractéristiques de la pile.
(KO) 본 발명에서는 리튬 복합금속 산화물을 포함하는 코어; 및 상기 코어의 표면상에 위치하는 표면처리층을 포함하고, 상기 표면처리층은 중심 금속 이온이 유기 리간드와 배위 결합한 다공성 배위 고분자를 포함함으로써, 전극 제조시 높은 전극밀도를 나타낼 수 있고, 그 결과 전지 특성을 크게 향상시킬 수 있는 이차전지용 양극활물질, 이를 포함하는 이차전지용 양극 및 이차전지가 제공된다.
