Abstract

A separator for charge device consisting of a cellulose microporous film, characterized in that the separator has a film thickness of 1 to 30 μm, a porosity of 20 to 90% and a maximum pore diameter of 2 μm or less, and that the apparent activation energy (-ΔG) relating to ion conduction at temperature ranging from 120° to 180°C is a positive value.
