Abstract
Methods for preparing an electrode for a secondary battery are provided herein. In some embodiments, the method includes coating a current collector with an electrode slurry to form a coating layer on the current collector, the electrode slurry including a binder, an electrode active material, a conductive material, and amorphous selenium nanoparticles, and a solvent; and drying the coating layer, wherein the drying vaporizes the amorphous selenium nanoparticles and forms a passageway in the coating layer.
