Abstract

A method of manufacturing a high loading electrode, which prevents the phenomenon of the binder being lifted, does not cause drying of the electrode slurry, and does not cause damage of the electrode layer and reduction of the electrode strength at the corners in the punching is provided. The method of manufacturing the high loading electrode includes applying an electrode slurry on a release film to thereby produce an electrode layer having the release film attached thereto, punching the electrode layer having the release film attached thereto to provide a plurality of punched electrode layers, each punched electrode layer having a size of a unit electrode, separating and removing the release film from the punched electrode layers, and stacking and rolling at least two punched electrode layers on a current collector.
