SOLID-STATE BATTERY AND METHOD FOR MAKING THE SAME

Abstract:

To provide a solid-state battery capable of applying an initial load that results in sufficient surface pressure to a battery cell, and a method for making the solid-state battery. A pressing part is provided in the solid-state battery case and the force of the spring is utilized, and a gas vent port is provided to replace gas or perform depressurization. Specifically, a solid-state battery including a solid-state battery cell and a battery case that houses the solid-state battery cell, is provided. A pressing part that applies surface pressure to the solid-state battery cell is formed on a surface constituting the battery case that is substantially perpendicular to the laminating direction of a laminate constituting the solid-state battery cell, and at least one gas vent port is formed in the battery case.
