NON-WOVEN FABRIC FOR SEPARATOR OF NON-AQUEOUS ELECTROLYTE CELL, AND NON-AQUEOUS ELECTROLYTE CELL USING THE SAME |
摘要 |
A non-woven fabric for a non-aqueous electrolyte cell capable of providing a non-aqueous electrolyte cell, which has high adhesion with an electrode, does not cause breakage of a separator and deviation and gap between the electrode and the separator, has high cell processability such as windability on the electrode, does not cause internal short-circuit due to mutual contact of the electrodes resulting from shrinkage and combustion of the non-woven fabric even when the electrodes are heated due to external short-circuit, can prevent combustion of the cell, is free from pin holes, and has excellent electrolyte retaining property and electrolyte permeation property, and can provide a non-aqueous electrolyte cell having excellent current capacity, cell characteristics and cell preservation characteristics. The present invention provides also a non-aqueous electrolyte cell using the non-woven fabric. More concretely, the non-woven fabric for a non-aqueous electrolyte cell separator according to the present invention has a film thickness non-uniformity index Rpy of not greater than 1,000 mV or a center surface mean roughness SRa of not greater than 6 mu m in the full wave region measured by using a probe type three-dimensional surface roughness meter. |
