SOLID-STATE BATTERY

Abstract:

The present invention decreases internal resistance in a solid-state battery having a LiAl system negative electrode mixture. A solid-state battery (1) includes: a positive electrode layer (20), a negative electrode layer (30), and a solid electrolyte layer (40) disposed between the positive electrode layer (20) and negative electrode layer (30), in which the negative electrode layer (30) includes an aluminum layer (31) contacting the solid electrolyte layer (40), and an aluminum-lithium alloy layer (33).
