Abstract
A battery interseparator useful in alkaline battery systems, and a process of forming the same, is formed from a composition having 30-70% by weight synthetic pulp, 15-65% by weight alkali resistant inorganic filler, and 1-35% by weight of long fibers having lengths of between 1/4 and 1 inch. The long fibers may be polyester, polyacrylic, polyamide, polyolefin, or other staple fiber material. The process for forming the subject battery interseparator requires first forming a substantially uniform aqueous mixture of the subject composition, sequentially treating said composition with a combination of a cationic and an anionic agent, applying the treated composition to a standard paper-making apparatus at a grammage rate to cause the resultant dried sheet to have a thickness of less than 10 mils, and forming a sheet product.
