PROBLEM TO BE SOLVED: To provide an electrode sticking method for a flexible battery which can avoid the use of an adhesive, and can effectively reduce a thickness of a flexible battery.SOLUTION: An electrode sticking method for a flexible battery includes: a step A of preparing a positive electrode plate and a negative electrode plate that are metal sheets, of which both ends are a conductive portion and a contact portion, where the contact portion has a first surface and a second surface positioned in an opposite side to the first surface, and an activator is applied to the first surface, and the second surface has a roughed surface; a step B of arraying the positive electrode plate and the negative electrode plate so as to be adjacent to each other, directing the second surface upward, covering the contact portions of the positive electrode plate and the negative electrode plate with an aluminum foil, not covering at least a part of the conductive portions of the positive electrode plate and the negative electrode plate with the aluminum foil, and bringing a surface that is directed downward of the aluminum foil in contact with the second surfaces of the positive electrode plate and the negative electrode plate; and a step C of heating and pressurizing the aluminum foil downward by a thermally pressurizing device, and thereby sticking a resin layer to the second surfaces of the positive electrode plate and the negative electrode plate.SELECTED DRAWING: Figure 5 |
