ALL-SOLID-STATE BATTERY, MANUFACTURING METHOD OF ALL-SOLID-STATE BATTERY, BASE POWDER, AND PRODUCTION METHOD OF BASE POWDER

Japanese Patent JP2023049671

A

To provide an all-solid-state battery in which a decrease in ionic conductivity can be suppressed while an amount of Ge is reduced, a manufacturing method of an all-solid-state battery, base powder, and a production method of base powder.SOLUTION: An all-solid-state battery includes a solid electrolyte layer, a first electrode layer which is provided on a first main surface of the solid electrolyte layer and contains an electrode active material, and a second electrode layer which is provided on a second main surface of the solid electrolyte layer and contains an electrode active material. A solid electrolyte that is a main component of the solid electrolyte layer has a structure represented by (Li1+x+(4-A)yAlxMyGe2-x-y(PO4)3), and is formed of a glass ceramic in which a portion of glass is crystallized. The A represents the valence of the M that is metal, and 0
