Abstract

PURPOSE: To obtain the separator with good electrolyte permeability and with small internal resistance by coating adhesives linearily on one side of beltlike separator base paper, spirally winding this base paper facing its coating surface inside, and making it cylindrical.
CONSTITUTION: Adhesives is linearily coated on one side of the paper type or felt type beltlike selarator base paper 1 consisting of natural cellulose fiber, vinylon, nylon, polyethylene, and polypropylene nonwoven fabrics. This base paper 1 partially overlaps with the rod-shaped body 3 and is spirally wound. Then, the rod-shaped body 3 is removed and the cylindrical body 4 is formed and cut off in specified dimensions. The adhesives 2 is linearily coated toward the longitudinal, traverse, or oblique direction of the base paper, not on both side ends of the base paper or on the inside except for both side ends. The adhesives can linearily be coated, as shown by a dashed line. This reduces the volume of adhesives. As a result, the cylindrical separators with good electrolyte permeability, with small internal resistance, and with easy production can be obtained.
