Abstract: front page image
(EN)The present invention relates to: a porous film obtained by laminating a first microporous layer containing a polyethylene-based polymer and first pore-forming particles and a second microporous layer containing a polypropylene-based polymer and second pore-forming particles, wherein the first pore-forming particles and the second pore-forming particles have an average particle diameter of 300 nm or less, the first pore-forming particles being contained in 5-25 vol% on the basis of the total volume of the first microporous layer, the second pore-forming particles being contained in 5-25 vol% on the basis of the total volume of the second microporous layer; a method for manufacturing the porous film; and a separator or electrochemical cell comprising the porous film.
(FR)La présente invention concerne : un film poreux obtenu par stratification d'une première couche microporeuse contenant un polymère à base de polyéthylène et des premières particules formant des pores et d'une seconde couche microporeuse contenant un polymère à base de polypropylène et des secondes particules formant des pores, lesquelles premières particules formant des pores et lesquelles secondes particules formant des pores ont un diamètre moyen des particules inférieur ou égal à 300 nm, les premières particules formant des pores étant contenues dans 5 à 25 % en volume sur la base du volume total de la première couche microporeuse, les secondes particules formant des pores étant contenues dans 5 à 25 % en volume sur la base du volume total de la seconde couche microporeuse ; un procédé de fabrication du film poreux ; et un séparateur ou une cellule électrochimique comprenant le film poreux.
(KO)폴리에틸렌계 폴리머 및 제1 기공형성 입자를 포함하는 제1 미다공층과, 폴리프로필렌계 폴리머 및 제2 기공형성 입자를 포함하는 제2 미다공층이 적층된 다공성 필름으로, 상기 제1 기공형성 입자 및 제2 기공형성 입자의 평균 입경은 300 nm 이하이고, 상기 제1 미다공층의 전체 부피를 기준으로 제1 기공형성 입자가 5 부피% 내지 25 부피%로 포함되고, 상기 제2 미다공층의 전체 부피를 기준으로 제2 기공형성 입자가 5 부피% 내지 25 부피%로 포함되는 다공성 필름, 다공성 필름의 제조 방법, 및 상기 다공성 필름을 포함하는 분리막 또는 전기화학 전지에 관한 것이다.
