1. A method for rolling an electrode, the method comprising:
preparing an electrode specimen by applying an electrode slurry containing an electrode active material on a current collector;
measuring a rheological property of the electrode specimen according to a temperature;
deriving an appropriate temperature condition for rolling an electrode from the rheological property of the electrode specimen according to the temperature; and
manufacturing the electrode and rolling the electrode under the appropriate temperature condition.
