Document Type and Number:
Japanese Patent JP5857935
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electrode manufacturing method capable of restraining warpage of an electrode.SOLUTION: A positive electrode manufacturing method has: a coating step of forming first and second coating parts G1, G2 on first and second faces 22a, 22b of a metallic foil 22 for a positive electrode; and a primary firing step of heating the first and second coating parts G1, G2 while the metallic foil 22 for the positive electrode is taken up by a take-up roll for primary firing. Also, the positive electrode manufacturing method has: a re-winding step of re-winding the metallic foil 22 for the positive electrode around a take-up roll 48 for secondary firing by reversing the metallic foil on top and back surfaces under a take-up state in the primary firing step; and a secondary firing step of heating the first and second coating parts G1, G2 while the metallic foil 2 for the positive electrode is wound around the take-up roll 48 for secondary firing.
