Document Type and Number:
WIPO Patent Application WO/2006/101243
Kind Code:
A1
Abstract:
This invention provides a composite sheet that can be used in condensers, capacitors, and batteries, is satisfactorily effective for high energy and large output, and, at the same time, has both shutdown and high-temperature shape stability, and is suitable as a separator for rechargeable batteries and capacitors. The composite sheet has a layer structure of at least two layers of a porous sheet layer of a thermoplastic polymer having a melting point of 200ºC or below, and a nonwoven fabric sheet formed of a fibrid or a short fiber or fibrillated pulp of an organic compound layer not having a substantially stable melting point stacked on top of each other.
