Disclosed are an electrode-membrane composite and a method of manufacturing the same, which can improve performance and safety of an electrochemical device. The electrode-membrane composite, the electrode; And an ultrafine fibrous porous polymer separator coated on the electrode and including two or more kinds of polymer layers having different characteristics. In addition, the manufacturing method of the electrode-membrane composite, (a) applying a slurry containing an electrode active material to a current collector and dried to produce an electrode; And (b) sequentially electrospinning two or more kinds of polymers having different characteristics on the surface of the electrode to coat the porous polymer separator on the ultra-fine fibers.n n n n Electrodes, separators, composites, polymer separators, electrospinning |
