In order to improve the linearity of lithium ion in the electrode, the amorphous selenium nanoparticles are added to the electrode active material, the conductive material and the binder, and the selenium nanoparticles are vaporized Thereby producing an electrode having a passageway. The method for manufacturing an electrode for a secondary battery includes the steps of: preparing a binder solution by dispersing or dissolving a binder in a solvent; Preparing an electrode slurry by mixing the binder solution with an electrode material including an electrode active material, a conductive material, and amorphous selenium nanoparticles; Coating the electrode slurry on a current collector; And vaporizing the amorphous selenium nanoparticles while drying the coating to foam the coating layer. |
