Abstract:
(EN) The present invention relates to: a porous film comprising polyethylene and pore-generating particles, wherein the porous film has a structure comprising lamella and fibril, and the average size of pores located inside the porous film is larger than the average size of pores located on the surface of the porous film; a separator comprising the same; and an electrochemical cell.
(FR) La présente invention concerne : un film poreux comprenant du polyéthylène et des particules générant des pores, le film poreux ayant une structure comprenant des lamelles et des fibrilles, et la taille moyenne des pores situés dans le film poreux étant supérieure à la taille moyenne des pores situés sur la surface du film poreux; un séparateur comportant un tel film; et un élément électrochimique.
(KO) 폴리에틸렌, 및 기공 형성 입자를 포함하는 다공성 필름으로, 상기 다공성 필름은 라멜라(lamella)와 피브릴(fibrill)을 포함하는 구조를 가지고, 상기 다공성 필름의 내부에 위치한 기공의 평균 크기는 상기 다공성 필름의 표면에 위치한 기공의 평균 크기보다 큰 다공성 필름과 이를 포함하는 분리막 및 전기 화학 전지에 관한 것이다.
