Secondary Battery Dry Electrode Manufacturing Method

Abstract: The present invention relates to a secondary battery dry electrode, a manufacturing method therefor, and a secondary battery comprising same. The dry electrode manufacturing method according to one aspect of the present invention comprises the steps of: (S1) obtaining powder for a first electrode from a mixture containing an active material and a binder; (S2) obtaining a mixture lump by kneading the powder for the first electrode and powder for a re-use electrode; (S3) obtaining powder for a second electrode by pulverizing the mixture lump; (S4) calendering the powder for the second electrode so as to obtain an electrode film; and (S5) positioning and laminating the electrode film on at least one surface of a current collector.
