Abstract
A method for applying an electrode mixture paste includes unwinding a core material wound in a coil shape; applying an electrode mixture paste to both sides of the core material; adjusting an application amount of the electrode mixture paste; drying a paste-coated sheet with the electrode mixture paste applied to the both sides thereof; and winding the paste-coated sheet in a coil shape. The electrode mixture paste is circulated and supplied by a circulation means having a storage function and a stirring function. 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.
