Abstract:
A method for producing a secondary battery electrode, according to the present invention, comprises: a slicing step for producing an active material film by slicing an active material bulk; and a binding step for combining a current collector and the active material film. A method for producing a secondary battery electrode according to the present invention produces an active material film by slicing an active material bulk, which is a free-standing molded body or pellet, thus allowing binder-free active material film to be produced, and as no actual restrictions exist for the thickness of the active material film, thick active material film can be produced, and thus electrodes having high-loading and high composite density can be produced.
