Abstract

PURPOSE:To improve the electrolyte holding characteristic by depositing metal hydroxcide on woven or unwoven cloth of polypropylene to provide hydrophilic performance. CONSTITUTION:Metal hydroxcide such as nickel hydroxcide is deposited in spot at the inner section of woven or unwoven polypropylene cloth to produce a separator having hydrophilic performance. Then polypropylene cloth is immersed in nickel nitrate solution, for example, thereafter it is washed with water and dried. Then it is immersed in caustic potash solution to neutralize, thereafter thus produced nickel hydroxcide is deposited at inner portion of cloth to obtain a separator for spiral Ni-Cd cell.
