In situ X-ray computational tomography measurement of single particle behavior of sulfide solid electrolyte under high-pressure compression
High-pressure in situ X-ray computational tomography measurements of sulfide solid electrolyte were conducted to elucidate the behavior of a single particle. Chlorine in Li6PS5Cl solid electrolyte was replaced by iodine to obtain high-contrast X-ray computational tomography measurements, and the behavior of a single particle under high pressure was successfully visualized. The experimental results were statistically analyzed to extract the generalized behavior of a solid electrolyte particle. The results show that pressurization increased the contact area and sphericity of a solid electrolyte particle and suppressed the voids between and within the solid electrolyte particles, thereby enhancing ionic conductivity.
