  • Publication number: 20190054495
    Abstract: A power storage device and an applicator is obtained that achieve an increase in capacity and an improvement in productivity, and that enable the thickness of a mixture layer to be inhibited from varying. A positive electrode mixture slurry is discharged into discharge regions of a belt-like positive electrode current collector that extend in a length direction of the positive electrode current collector from discharge nozzles corresponding to the respective discharge regions to form a positive electrode mixture layer on the positive electrode current collector. The discharge regions are arranged such that a part of each of the discharge regions overlaps a part of another of the discharge regions adjacent thereto when viewed in the length direction to form overlapping portions. The positive electrode mixture slurry is intermittently discharged to form an exposed portion on at least one of the discharge regions.
