"highly deformable solid electrolyte and carbon... construct both electrodes for bulk-type solid-state capacitor. This capacitor is capable of high current densities and high-capacity charging and discharging at temperatures of 200-300°C, creating... bulk-type solid-state capacitors... capacitor... improve technology for high-temperature environments, which could not be developed previously due to these technical limitations... combine excellent deformability and lithium-ion conductivity... apply to capacitors"
