<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of an electrode plate capable of forming the electrode which is a thinly coated activator layer with excellent surface quality, having high uniformity of film thickness, high conductivity, and high safety, as well as an electrode plate suited for high-output use, and a nonaqueous electrolyte solution secondary battery. <P>SOLUTION: A coating composition for an activator layer of which, a maximum particle size (D<SB>90</SB>) of activator contained therein is less than a gap (G) between a tip of a die head (1a) and a coating face of a collector (A), and less than a target thickness (T2) of the activator layer after a pressing process; and at the same time, a central particle size (D<SB>50</SB>) is not more than a half of the target thickness of the active material layer after the pressing process; is used for the electrode plate. A solid portion of a coating volume of the coating composition of the activator is made 110g/m<SP>2</SP>or less in case of a cathode, and 40g/m<SP>2</SP>or less in case of an anode. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
