<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of an electrode for a non-aqueous electrolyte secondary battery in which a non-coated portion does not arise and the thickness of coating is uniform, at the manufacturing of the electrode by intermittently coating an active material mixture slurry on a current collector using a die-coater equipped with a decompression chamber. <P>SOLUTION: This is the manufacturing method of an electrode for the non-aqueous electrolyte secondary battery having a process in which a belt shape drying body is formed by coating intermittently an active material mixture slurry of the non-aqueous electrolyte secondary battery on a belt-shape current collector using a die-coater 13. A decompression chamber in which the upstream side portion on the current collector located near the die-coater 13 is made a decompressed state by suction is provided and the suction of the decompression chamber is controlled to start immediately before coating of the active material mixture slurry and to stop immediately before completion of coating. The die-coater 13 is used of which the width W of the inner side face of a guide 30 to define the coating width of the die-coater decreases linearly from a manifold 18 to an injection port 33, and the opening edge 34 of the guide 30 is not chamfered. <P>COPYRIGHT: (C)2008,JPO&INPIT |
