Method for dry-manufacturing secondary battery electrode

A method for manufacturing a dry electrode for a secondary battery, the method comprising the steps of:

• a. mixing active materials and binders to make a mixture and putting the mixture to a screw mixer;
• b. rotating the screw mixer to move the mixture forward and allowing the mixture to be primarily heated and melted;
• c. rotating the screw mixer to move the heated and melted mixture forward and allowing the mixture to be agitated;
• d. rotating the screw mixer to move the agitated mixture forward and allowing the mixture to be secondarily heated and agitated;
• e. rotating the screw mixer to pressurize the secondarily heated and agitated mixture forward and allowing the mixture to move to the end of a nozzle;
• f. allowing the mixture discharged to the form of a film through the nozzle to be compressed through rollers located above and under the mixture;
• and
• g. attaching the film to a metal foil to manufacture the dry electrode.
