摘要： An electrochemical device includes an electrode structure provided with a composite separator having a porous substrate with 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 electrode active material particles and a binder polymer. The porous coating layer of the composite separator improves thermal stability of the porous substrate and plays a function of electrode active material layer of the electrochemical device. Accordingly, this electrochemical device has excellent stability and good economical efficiency since the electrode structure does not need coating of an electrode active material layer on a surface of a current collector.

摘要： Provided is an electrochemical device comprising two types of separators having different energy to break, wherein the outermost electrode layer of the electrode assembly includes an active material non-coated cathode, an active material non-coated anode, and a separator (second separator) disposed between the cathode and anode and having relatively low energy to break compared to that of separators (first separator) in other electrode layers. Therefore, it is possible to remarkably improve safety of the battery by inducing primary short-circuiting in the outermost electrode layer of a battery, thus facilitating heat dissipation of the battery, upon application of external impact.

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 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 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.
