摘要： Disclosed is a separator. The separator includes a planar non-woven fabric substrate having a plurality of pores, and a porous coating layer formed on at least one surface of the non-woven fabric substrate. The porous coating layer is composed of a mixture of filler particles and a binder polymer. The filler particles include conductive positive temperature coefficient (PTC) particles composed of a mixture of conductive particles and a low melting point resin having a melting point lower than that of the non-woven fabric substrate. Due to the presence of the conductive PTC particles, the porous coating layer can be imparted with a shutdown function against thermal runaway. In addition, the porous coating layer exhibits appropriate electrical conductivity. Therefore, the separator is suitable for use in a high-capacity electrochemical device.

摘要： A method for manufacturing an electrode may include (S1) preparing a sol solution containing a metal alkoxide compound, and (S2) forming a porous non-woven coating layer of an inorganic fiber by electroemitting the sol solution onto an outer surface of an electrode active material layer formed on at least one surface of a current collector. The porous non-woven coating layer formed on the outer surface of the electrode active material layer may be made from an inorganic fiber having excellent thermal stability. When an electrochemical device is overheated, the porous non-woven coating layer may contribute to suppression of a short circuit between a cathode and an anode and performance improvement of an electrochemical device due to uniform distribution of pores.
