說(shuō)明書
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 press-molding a raw material including a particulate electrode active material and a carbon precursor to produce a molded body; and heat-treating the molded body to pyrolyze the carbon precursor into carbon.
In the method of producing an electrode for a secondary battery according to an exemplary embodiment of the present invention, the molded body may be produced by unidirectional, bidirectional, or isotropic compression molding.
In the method of producing an electrode for a secondary battery according to an exemplary embodiment of the present invention, a step of surface-treating at least one surface of the active material film may be further performed, after the cutting step and before the binding step, or after the binding step.
In the method of producing an electrode for a secondary battery according to an exemplary embodiment of the present invention, the surface treatment may include surface roughness adjustment.
In another general aspect, an electrode for a secondary battery produced by the production method described above is provided.
In another general aspect, a lithium secondary battery includes: a positive electrode; a negative electrode; a separator interposed between the positive electrode and the negative electrode; and an electrolyte solution, wherein one or more electrodes selected from the positive electrode and the negative electrode may include an active material film containing an electrode active material, a current collector, and an adhesive for adhering the active material film to the current collector.
