ELECTRODE MIXTURE PASTE APPLYING METHOD |
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) 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 (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 the second step, the electrode mixture paste is circulated and supplied by circulation means (9, 10), and the circulation means has a storage function (9) and a stirring function (11). The application method can achieve stable application accuracy even when a paste-coated sheet is continuously produced using a plurality of lots of electrode mixture pastes containing different types of powders having a large difference in the specific gravity. |
