PRESSURIZATION MECHANISM AND TESTING APPARATUS FOR ALL-SOLID-STATE BATTERY

A pressurization mechanism for an all-solid-state battery including an all-solid-state battery cell arranged inside a fluid chamber filled with fluid, and a pressurization part having the fluid chamber and applying a predetermined pressure to the all-solid-state battery cell via the fluid. The fluid may be oil. The predetermined pressure may be generated by applying pressure to the fluid chamber. The pressurization part may include an upper shell member, a lower shell member, and a metal bellows arranged in a space defined by the upper shell member and the lower shell member.
