    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 separator includes a planar non-woven fabric substrate having a plurality of pores, and a porous coating layer provided on at least one surface of the non-woven fabric substrate and made of a mixture of a plurality of inorganic particles and a binder polymer, wherein the non-woven fabric substrate is made of superfine fibers having an average thickness of 0.5 to 10 μm, and wherein, among the pores in the non-woven fabric substrate, pores having a wide diameter of 0.1 to 70 μm are 50% or above of the entire pores. The above separator having the porous coating layer may generate the generation of leak current without increasing a loading weight of the porous coating layer since the non-woven fabric substrate having a controlled pore side by using superfine fibers of a predetermined thickness is used.

    摘要: The present invention provides a cathode comprising two or more lithium-containing metal composite oxides, having different potentials versus lithium (Li/Li+) and different impedances, the cathode comprising: (a) a first lithium-containing metal composite oxide; and (b) a second lithium-containing metal composite oxide, which has a high impedance and low potential versus lithium (Li/Li+), compared to those of the first lithium-containing metal composite oxide. In the invention, two or more lithium-containing metal composite oxides are used in combination as cathode components in a battery, whereby, when a short circuit occurs in the battery, the instantaneous flow of a large amount of current can be minimized and, at the same time, the accumulation of heat in the battery can be reduced, thus ensuring the safety of the battery.
