摘要
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.

In contrast, the adhesive layer is formed so that each of the two surfaces opposing each other of the current collector is in contact with the active material film with the adhesive layer interposed therebetween in step c1), and the adhesive layer and the active material film are layered so as to form a sandwich structure with the current collector being in the center in step c2), thereby adhering the active material film to each of the two surfaces opposing each other of the current collector.
As described above, the active material film of the electrode may be a film capable of free-standing, and it may be a cut film sliced from a molded body as shown in
