Zusammenfassung: | To provide a method for manufacturing an electrode capable of suppressing quality deterioration.SOLUTION: A method for manufacturing an electrode includes the steps of: preparing a precursor sheet including a metal foil having a longitudinal direction in a first direction and a coated part and an uncoated part arranged on the metal foil; pressing the coated part in a thickness direction while transporting the precursor sheet in the first direction; and pressing the uncoated part in the thickness direction while transporting the precursor sheet in the first direction before or after the coated part pressing step. The uncoated part is arranged in an end part of the coated part in a direction orthogonal to the first direction. In the uncoated part pressing step, the method performs roll-press while applying compressive force for pressing the uncoated part in the thickness direction using a pair of elastic rolls having a shaft body and an elastic body covering the shaft body. The method uses elastic rolls A and B as a pair of elastic rolls. A Young's modulus X of the elastic body in the elastic roll A is lower than a Young's modulus Y of the elastic body in the elastic body B.SELECTED DRAWING: Figure 1
【課題】品質劣化を抑制できる電極の製造方法の提供。【解決手段】第1方向に長手方向を有する金属箔と、金属箔上に配置された塗工部および未塗工部とを有する前駆体シートを準備する工程、前駆体シートを第1方向に搬送しながら、塗工部を厚さ方向にプレスする工程、塗工部プレス工程の前または後に、前駆体シートを第1方向に搬送しながら未塗工部を厚さ方向にプレスする工程を有し、第1方向と直交する方向における塗工部の端部に配置され、未塗工部プレス工程において、軸体と、軸体を覆う弾性体とを有する一対の弾性ロールを用いて、未塗工部を厚さ方向に押し付ける圧縮力を付与しつつロールプレスし、一対の弾性ロールとして、弾性ロールAおよび弾性ロールBを用い、弾性ロールAにおける弾性体のヤング率Xは、弾性ロールBにおける弾性体のヤング率Yよりも低い、電極の製造方法とする。【選択図】図1 |
