Stage: PROBLEM TO BE SOLVED: To prevent cracking by suppressing stress concentration in a solid electrolyte layer during charging and discharging.SOLUTION: A battery cell 1 is composed of a cathode current collector 2, a solid electrolyte layer 4, and an anode current collector 5, stacked on top of each other. Furthermore, the battery cell 1 includes a cathode layer 3 provided between the cathode current collector 2 and the solid electrolyte layer 4, the outer edge of the surface facing the solid electrolyte layer 4 having an inclined surface 3b that slopes toward the cathode current collector 2 as it moves outward and an ion conductor layer 6 that covers the inclined surface 3b of the cathode layer 3 and has a lower Young's modulus than the solid electrolyte layer 4.SELECTED DRAWING: Figure 1 (Grant)
