POSITIVE ELECTRODE FOR SOLID-STATE BATTERY, MANUFACTURING METHOD OF POSITIVE ELECTRODE FOR SOLID-STATE BATTERY, AND SOLID-STATE BATTERY

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.
