說(shuō)明書(shū)
In one general aspect, a method of producing an electrode for a secondary battery includes: a cutting step of slicing an active material bulk to produce an active material film; and a binding step of integrating a current collector and the active material film.
The method of producing an electrode for a secondary battery according to an exemplary embodiment of the present invention may further include a bulk production step of using a raw material including a particulate electrode active material to produce an active material bulk, before the slicing.
In the method of producing an electrode for a secondary battery according, to an exemplary embodiment of the present invention, the electrode active material may be a negative electrode active material or a positive electrode active material.
In the method of producing an electrode for a secondary battery according to an exemplary embodiment of invention, the active material bulk may be capable of free-standing.
In the method of producing an electrode for a secondary battery according to an exemplary embodiment of the present invention, the active material bulk may be a molded body or a sintered body.
In the method of producing an electrode for a secondary battery according to an exemplary embodiment of the present invention, the bulk production step may include a molding step of compression-molding the raw material to produce a molded body; or may include the molding step and a sintering step of heat-treating the molded body produced in the melding step to produce a sintered body.
