摘要： A separator includes a non-woven fabric substrate having pores, fine thermoplastic powder located inside the pores of the non-woven fabric substrate, and a porous coating layer disposed on at least one surface of the non-woven fabric substrate. The fine thermoplastic powder has an average diameter smaller than that of the pores and a melting point lower than the melting or decomposition point of the non-woven fabric substrate. The porous coating layer includes a mixture of inorganic particles and a binder polymer whose melting point is higher than the melting or decomposition point of the fine thermoplastic powder. In the porous coating layer, the inorganic particles are fixedly connected to each other by the binder polymer and the pores are formed by interstitial volumes between the inorganic particles. Previous filling of the large pores of the non-woven fabric substrate with the fine thermoplastic powder makes the porous coating layer uniform.

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.

摘要： A separator includes a porous substrate having a plurality of pores, and a porous coating layer formed on at least one surface of the porous substrate and made of a mixture of a plurality of filler particles and a binder polymer. The filler particles include electrode active material particles that are electrochemically oxidized and reduced. The binder polymer includes a copolymer having (a) a first monomer unit with a contact angle to water of 0 to 49° and (b) a second monomer unit with a contact angle to water of 50 to 130°. This separator is useful for an electrochemical device, particularly a lithium secondary battery. This separator ensures improved thermal stability and increased capacity of the electrochemical device. Also, inorganic particles in the porous coating layer formed on the porous substrate are not disintercalated due to excellent peeling resistance of the porous coating layer while the electrochemical is assembled.
