POSITIVE ELECTRODE PLATE FOR ALL-SOLID-STATE BATTERY, AND ALL-SOLID-STATE BATTERY

摘要

A positive electrode plate (106) for an all-solid-state battery constitutes the positive electrode of an all-solid-state battery (100) that contains a solid-state electrolyte layer (107) comprising a lithium phosphate oxynitride ceramic material, wherein a solid-state electrolyte layer-side surface (106a), on which the solid-state electrolyte layer (107) is formed, has a surface roughness of 0.1 μm to 0.7 μm.
