AI Technical Summary
Existing stationary power storage devices with all-solid-state batteries face challenges in applying sufficient restraining forces to prevent deterioration, particularly due to swelling issues with Si-based anodes, and require effective temperature stabilization and hydrogen sulfide containment.
The device positions all-solid-state batteries between building pedestals with elastic bodies, utilizing a base structure that applies a high load of 1 MPa or more per electrode area, incorporates a waterproof member to contain hydrogen sulfide, and maintains stable underground temperatures.
This configuration effectively restrains all-solid-state batteries under high loads, stabilizes temperature, and contains hydrogen sulfide underground, enhancing safety and durability while minimizing space and weight, thus suppressing battery deterioration.
