发明名称 SEPARATOR FOR ENERGY STORAGE DEVICE
摘要 <p><P>PROBLEM TO BE SOLVED: To provide a separator for an energy storage device, which is formed as a thin film, has a shutdown function, and is superior in any of anti-thermal shrinkage properties, mechanical strength, and ion conductivity. <P>SOLUTION: The separator for the energy storage device is a laminate of a fiber layer including solvent spinning cellulose and a polyolefin-made porous film layer. Preferably, thermoelastic synthetic fiber A such as polyester, polyolefin, and the like is included in the fiber layer. Preferably, heat-resistant synthetic fiber B such as full aromatic polyamide, polyphenylene sulfide, and the like is included in the fiber layer. More preferably, the solvent spinning cellulose is formed as a fibril in which a fiber diameter is≤1μm and a fiber length is≤3 mm. <P>COPYRIGHT: (C)2011,JPO&INPIT</p>
