摘要:
A method for manufacturing an electrode disclosed herein includes: steps of forming a coating film composed of an electrode material by passing the electrode material through a gap between a rotating first roll and a rotating second roll; adhering the coating film to the second roll and conveying the coating film; and transferring the conveyed coating film onto an electrode current collector conveyed by a conveying device to form an electrode mixture layer composed of the coating film. The speed ratio between a peripheral speed of the second roll and a conveying speed of the electrode current collector is changed by changing the peripheral speed of the second roll on the basis of the thickness of the coating film or the width of the gap. The timing of the change in the speed ratio is allowed to be based on the Equation (1) described in the description.
