Abstract:
1. An electrode mixture paste application method for applying an electrode mixture paste on a core material made of porous metal thin plate while traveling the core material, the method comprising: a first step of unwinding the core material wound in a coil shape; a second step of applying the electrode mixture paste to both sides of the core material; a third step of adjusting an application amount of the electrode mixture paste; a fourth step of drying a paste-coated sheet with the electrode mixture paste applied to the both sides thereof; a fifth step of detecting a boundary between a mixture-formed portion and the core material; and a sixth step of winding the paste-coated sheet in a coil shape, wherein, in the sixth step, the paste-coated sheet is wound based on a detection result of the fifth step such that each of widthwise edge portions of the mixture-formed portion is prevented from sequentially overlapping itself.
