ORGANIC/INORGANIC COMPOSITE POROUS LAYER-COATED ELECTRODE AND ELECTRO-CHEMICAL DEVICE COMPRISING THE SAME |
摘要 |
Disclosed is an electrode comprising a first organic/inorganic composite porous coating layer formed on its surface, wherein the first coating layer includes inorganic particles and a binder polymer for interconnecting and fixing the inorganic particles, and has micropores formed by interstitial volumes among the inorganic particles. An electrochemical device including t he same electrode is also disclosed. Further, disclosed is a method for manufacturing an electrode having an organic/inorganic composite porous coating layer on the surface thereof, comprising the steps of: (a) coating a current collector with slurry containing an electrode active material and drying it to provide an electrode; and (b) coating the surface of electrode obtained from step (a) with a mixture of inorganic particles with a binder polymer. A lithium secondary battery including the electrode shows improved safety and minimized degradation in battery performance. |
