Title:

POSITIVE ELECTRODE, BATTERY, AND POSITIVE ELECTRODE MANUFACTURING METHOD

Document Type and Number:

WIPO Patent Application WO/2023/008119

Kind Code:

A1

Abstract:

A positive electrode 1000 comprises a mixture of a positive electrode active material 110, a solid electrolyte 100, and a conductive material 140. The conductive material 140 contains carbon black 150 having an average particle diameter of 100nm or less. When a cross-section of the positive electrode 1000 is observed using a scanning electron microscope, a region is observed between the positive electrode active material 110 and the solid electrolyte 100, the region having a concentration of carbon black 150 present therein.
