<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of an electrode for power storage device capable of shortening the drying time significantly. <P>SOLUTION: The manufacturing method of an electrode for power storage device having an electrode active material layer principally composed of an electrode active material comprises: a step of preparing a paste forming an electrode active material layer which is produced by dispersing an aggregate of a solid content material containing at least the electrode active material and a binder into a predetermined solvent; a step of coating the surface of a collector with the paste; and a step of forming an electrode active material layer composed of the solid content material in the paste by drying the collector coated with the paste. In the step of preparing the paste, the paste is prepared so that the ratio of the solid content material in the paste is 60-80 mass%, the abundance of the aggregate having a grain size of 20 μm or less is 99% by number or more, and the viscosity at 25°C and a shear rate of 40 s<SP POS="POST">-1</SP>is 200-5000 mPa s. <P>COPYRIGHT: (C)2013,JPO&INPIT |
