Abstract: A positive electrode for a solid-state battery, a manufacturing method of the positive electrode for the solid-state battery, and the solid-state battery are provided such that the occurrence of cracking during lamination pressing at the time of manufacturing the solid-state battery and short-circuiting due to contact with a tab can be suppressed.
A guide is provided on the outer periphery of a positive electrode active material layer, whereby pressure applied during the lamination pressing is dispersed, and short-circuiting due to contact with a tab is suppressed.
Specifically, the guide is provided on at least two adjoining sides of the outer periphery of the positive electrode active material layer of a surface having the positive electrode active material layer.

Abstract: Provided is a positive electrode manufacturing method including the step of mixing carbon particles, a first binder, a first dispersant, and a first solvent to form a first dispersion, the step of mixing carbon nanotubes, a second binder, a second dispersant, and a second solvent to form a second dispersion, the step of mixing one of the first dispersion or the second dispersion with a positive electrode active material to form a third dispersion, the step of mixing the other one of the first dispersion or the second dispersion with the third dispersion to form a fourth dispersion, and the step of applying the fourth dispersion to a positive electrode current collector to form a positive electrode material mixture layer.
