Abstract:

Provided are: a solid-state battery in which an initial load is applied to a battery cell; and a solid-state battery module comprised of the battery. This solid-state battery includes a pressing portion provided on a solid-state battery case so that a spring force is utilized to apply the initial load to the solid-state battery. Specifically, the solid-state battery includes a solid-state battery cell, and a battery case for accommodating the solid-state battery cell, in which the solid-state battery cell is a stack including a positive electrode, a negative electrode, and a solid electrolyte present between the positive electrode and the negative electrode, and in which a face constituting the battery case and extending substantially perpendicular to the stacking direction of the stack has a pressing portion.
