摘要： Disclosed is an electrode whose surface includes an organic/inorganic composite porous coating layer comprising porous inorganic particles and a binder polymer, wherein the porous inorganic particles have pores having such a size that lithium ions (Li+) solvated in an electrolyte solvent can pass therethrough. A method for manufacturing the electrode and an electrochemical device using the electrode are also disclosed. The organic/inorganic composite porous coating layer formed on the electrode according to the present invention provides an additional pathway for lithium ion conduction due to a plurality of pore structures present in the porous inorganic particles. Thus, when the organic/inorganic composite porous coating layer is used instead of a conventional polymer-based separator in a battery, the battery can provide improved quality and an increased energy density per unit weight due to a reduced weight of the organic/inorganic composite porous coating layer.

摘要： A separator includes a porous substrate having a plurality of pores; a porous coating layer formed on at least one surface of the porous substrate and made of a mixture of a plurality of inorganic particles and a binder polymer; and a dot pattern layer formed on a surface of the porous coating layer and having a plurality of dots made of polymer and arranged at predetermined intervals. The separator may control short-circuit between positive and negative electrodes though an electrochemical device is overheated. Also, a united force to an electrode is enhanced due to the polymer dot pattern layer, thereby preventing the electrode and the separator from being separated. Accordingly, inorganic particles of the porous coating layer formed on the porous substrate are not separated, thereby improving stability of an electrochemical device.
