Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for preparing an electrode for a secondary battery, comprising: 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 to vaporize the amorphous selenium nanoparticles and form a passageway in the coating layer. 2. The method for preparing an electrode for a secondary battery of claim 1 , wherein a size of the amorphous selenium nanoparticles is in a range of 500 nm to 1000 nm. 3. The method for preparing an electrode for a secondary battery of claim 1 , wherein the coating layer is dried at 90 to 110° C.
