However, even in the case in which a novel material having a high capacity is developed, a conventional technique of producing an electrode by applying a slurry containing an active material, a binder, and a conductive material to a current collector, and performing drying and rolling has limitation on implementation of an electrode having a high mixture and high density, due to the problems that when the electrode is manufactured with a high mixture density, voids are blocked so that electrolyte solution impregnation becomes difficult to decrease mobility of lithium ions, and an active material is pressed in a direction parallel to a current collector by rolling, so that a travel distance of lithium ions becomes longer and path complexity (tortuosity) is increased.
An object of the present invention is to provide a method of producing a novel electrode for a secondary battery allowing implementation of high loading and a high mixture density.
Another object of the present invention is to provide a method of producing a novel electrode for a secondary battery allowing implementation of a binder-free electrode in which an active material layer contains no binder.
Another object of the present invention is to provide a method of producing a novel electrode for a secondary battery which may reduce costs by a more simplified process and allow mass production of electrodes having uniform quality.
Still another object of the present invention is to provide an active material film on which an electrode having high loading and high mixture density may be implemented, an electrode for a secondary battery including the same, and a secondary battery including the same.
