PROBLEM TO BE SOLVED: To improve quality of an electrode sheet.SOLUTION: In a method for manufacturing an electrode sheet for a lithium ion secondary battery proposed here, reduction rolls 101, 102 are electrically charged. Next, powder 203, 204 are deposited on the charged rolls 101, 102. Then, the powder 203, 204 having been deposited on the reduction rolls 101, 102 are pressed against a current collector foil 201 to thereby transfer the powder 203, 204 on the current collector foil 201.SELECTED DRAWING: Figure 4 |
