Abstract: front page image
(EN)The present invention relates to a separator for an electrochemical device, the separator including a porous coating layer, comprising inorganic particles, positioned on the surface of a porous polymer substrate, wherein the porous coating layer comprises, as the inorganic particles, plate type inorganic particles and sphere type inorganic particles. The content of the plate type inorganic particles increases stepwise or sequentially from the lower part close to the porous polymer substrate to the upper part with respect to the thickness direction of the porous coating layer, and the content of b) inorganic particles decreases stepwise or sequentially from the lower part close to the porous polymer substrate to the upper part.
(FR)La présente invention concerne un séparateur pour un dispositif électrochimique, le séparateur comprenant une couche de revêtement poreux, comprenant des particules inorganiques, positionnée sur la surface d'un substrat polymère poreux, la couche de revêtement poreux comprenant, en tant que particules inorganiques, des particules inorganiques de type plaque et des particules inorganiques de type sphère. La teneur en particules inorganiques de type plaque augmente progressivement ou séquentiellement à partir de la partie inférieure proche du substrat polymère poreux à la partie supérieure par rapport à la direction de l'épaisseur de la couche de revêtement poreux, et le contenu de b) des particules inorganiques diminuent progressivement ou séquentiellement depuis la partie inférieure proche du substrat polymère poreux jusqu'à la partie supérieure.
(KO)본 발명은 전기화학소자용 분리막에 대한 것으로서, 상기 분리막은 다공성 고분자 기재의 표면에 무기물 입자를 포함하는 다공성 코팅층을 포함하며, 상기 다공성 코팅층은 무기물 입자로서 평판형 무기물 입자 및 구형 무기물 입자를 포함하고 다공성 코팅층의 두께 방향을 기준으로 다공성 고분자 기재와 가까운 하부로부터 상부에 이르기까지 상기 평판형 무기물 입자의 함량이 단계적으로 또는 순차적으로 증가하고, 다공성 고분자 기재와 가까운 하부로부터 상부에 이르기까지 b) 무기물 입자의 함량이 단계적으로 또는 순차적으로 감소하는 것을 특징으로 한다.
