ALL-SOLID-STATE BATTERY

摘要

Provided is an all-solid-state battery which is capable of having improved charge/discharge efficiency by adequately controlling the electron conduction and ion conduction within a negative electrode layer. An all-solid-state battery laminate(10) which is provided with a positive electrode layer (11), a negative electrode layer (12) and a solid electrolyte layer (13) that is interposed between the positive electrode layer (11) and the negative electrode layer (12). The negative electrode layer (12) contains a negative electrode active material and a solid electrolyte, and the area ratio occupied by the negative electrode active material is 72% or less in a surface of the negative electrode layer (12), said surface being on the reverse side of the solid electrolyte-side surface of the negative electrode layer (12).
