PROBLEM TO BE SOLVED: To provide a method for manufacturing a secondary battery, by which the performance degradation of the battery can be suppressed.SOLUTION: A method for manufacturing a secondary battery proposed here comprises: a stirring step where secondary particles 12 composed of aggregates of primary particles 10 of an active material are mixed and stirred with a conductive binder 14, thereby producing conductive binder-impregnated active material particles 16 with the conductive binder 14 impregnated into gaps among the primary particles 10; an isotropically compacting step where the conductive binder-impregnated active material particles 16 are isotropically compacted together; a coating step where an active material layer is formed; and a rolling step where the active material layer is rolled.SELECTED DRAWING: Figure 4 |
