METHOD AND DEVICE FOR APPLYING ELECTRODE MIX PASTE |
摘要 |
A method for applying an electrode mixture paste includes: a first step of unwinding a core material (2) wound in a coil shape; a second step of applying an electrode mixture paste (5) onto 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 (6) with the electrode mixture paste applied to the both sides thereof; and a fifth step of winding the paste-coated sheet in a coil shape. In this method, in one of the second and third steps, a core material-exposed portion (9) to which the electrode mixture paste is not applied is provided in both edge portions in a width direction of the core material, and, in the fourth step, a holding unit is provided in at least one position, the holding unit continuously holding the core material-exposed portion between a wheel type roller (10) and a contact belt (11) and changing a traveling direction of the paste-coated sheet. A stable electrode mixture paste application method can be achieved by preventing the occurrence of wrinkles formed when the electrode mixture paste containing a high specific gravity material is applied and dried in order to avoid the reduction in application accuracy due to the flow of the electrode mixture paste. |
