Abstract:
(EN) The present invention relates to a separation membrane for an electrochemical element, which comprises a nonwoven fabric substrate, wherein at least one side surface of the nonwoven fabric substrate comprises an electrode reaction layer formed by carbonizing the nonwoven fabric member from the surface thereof to a prescribed depth, and the electrode reaction layer is disposed at the outermost side of at least one surface of both surfaces of the separation membrane.
(FR) La présente invention concerne une membrane de séparation qui est destinée à un élément électrochimique et qui comprend un substrat en tissu non tissé, au moins une surface latérale du substrat de tissu non tissé comprenant une couche de réaction d'électrode formée par carbonisation de l'élément de tissu non tissé de sa surface à une profondeur prescrite, la couche de réaction d'électrode étant disposée sur le côté externe d'au moins une surface des deux surfaces de la membrane de séparation.
(KO) 본 발명은 전기화학소자용 분리막에 대한 것으로서 상기 분리막은 부직포 기재를 포함하며, 상기 부직포 기재의 적어도 일측 표면은 부직포 기재의 표면으로부터 소정 깊이까지의 부직포 기재가 탄화되어(carbonized) 형성된 전극 반응층을 포함하며, 상기 전극 반응층은 분리막의 양 표면 중 적어도 한쪽 표면의 최외측에 배치되는 것이다.
