Abstract
The present invention relates to a method for manufacturing an electrode having 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. The method comprises the steps of dispersing inorganic precursors and heat-decomposable compounds in a dispersion medium, misting the inorganic precursor solution, and performing a thermal decomposition and a crystallization processes, to thereby prepare porous inorganic particles, adding and mixing the porous inorganic particles to a polymer solution in which a binder polymer is dissolved, and coating the mixture onto a preliminarily formed electrode and drying the coating layer.
