Cellulosic Fibers for Alkaline Battery Separators

摘要

This article reports on a study which was carried out to compare different fibers properties and their influence on the battery separators performance. Amongst cellulosic fibers, Lenzing's TENCEL~R has a unique "fibrillation ability" and utilising the long and submicron "fibrils" it is possible to manufacture separators with small and uniform pores. In addition, the fibrils "interlace" together and create a 3D structure that ensures high dimensional stability. Work to improve TENCEL~R's properties is also described which has optimized the fiber for alkaline battery separators.
