Abstract

본 발명은 알카리 2차전지용 세퍼레이터 및 이의 제조방법에 관한 것으로, 좀 더 상세하게는 상기 세퍼레이터는 부직포의 표면에 스페이서가 형성되어 이루어진 것으로, 장시간 충방전 이후에도 전해액의 건조현상이 거의 나타나지 않기 때문에 전지가 제 용량을 충분히 발휘할수 있으므로 전지의 수명이 연장되며, 유리 전해액이 거의 발생되지 않기 때문에 산소가스의 투과가 굉장히 쉬어지므로 전지의 용량이 최대가 될 수 있다.The present invention relates to a separator for an alkaline secondary battery and a method of manufacturing the same. More specifically, the separator is formed by forming a spacer on the surface of the nonwoven fabric, and since the dryness of the electrolyte is hardly observed even after a long time charge and discharge, Since the capacity can be sufficiently exhibited, the life of the battery is extended, and since the glass electrolyte is hardly generated, permeation of oxygen gas is extremely easy, and thus the capacity of the battery can be maximized.
