Abstract
The present invention relates to a method for preparing a positive electrode, comprising preparing a mixture by dry mixing a positive electrode active material, a dry conductive material, and a dry binder, applying high shear force to the mixture, disposing the mixture on a current collector, and rolling the current collector on which the mixture is disposed, wherein the dry conductive material is at least any one of a carbon nanotube and a carbon fiber, and the high 10 shear force is 100 N to 500 N.
