CHARACTERIZATION OF CELLOPHANE AS AN IONIC BARRIER

Abstract

Cellophane, a gel developed from crystalline alphacellulose, has been used as an ionic barrier (battery separator) in electrical batteries with outstanding success for many years. Understanding the mechanism of the cellophane action in ionic barrier applications could lead to the development of superior ionic barriers. A literature survey has been conducted on the characteristics of cellophane as related to electrochemical cell barrier applications. The physical or chemical bonding of ions in electrolyte solutions to molecules in the membrane, or the catalytic complexing of undesirable ions appear to be much more important in the effective operation of cellophane as a barrier than the filtering or capillary diffusion actions, although these latter actions cannot be ignored.
