NONWOVEN FABRIC FORMED FROM FIBER COATED WITH ORGANIC BINDER POLYMER COMPOUND, ELECTROCHEMICAL DEVICE COMPRISING NONWOVEN FABRIC, AND METHOD FOR MANUFACTURING NONWOVEN FABRIC

摘要

The present disclosure relates to a non-woven fabric made from a fiber coated with a binder polymer by spinning a non-woven forming fiber in an organic binder polymer compound solution, an electrochemical cell using the non-woven fabric as a separator substrate, and a method of making the non-woven fabric, and the non-woven fabric has a pore diameter in a range of 0.001 to 10 µm, thereby providing a mechanical property required for a separator while ensuring a favorable movement of a lithium ion, and in the use of the non-woven fabric as a separator of an electrochemical cell, eliminating a need for a process of applying a separate adhesive layer, resulting in an effect of simplifying a separator manufacturing process.
