Abstract
- To mitigate poor contact issues between electrolyte/electrode materials interfaces of all‐solid‐state batteries (ASSB), we newly introduce a novel solution‐processed synthesis that exploits the differences in the boiling point and polarity of the two solvents (i. e., methanol, and toluene), with a cavitation effect by bubbling inert gas. Through this process, called solvent exchange with bubbles (SEB), the Li6PS5Cl solid electrolyte is synthesized with a particle size below 800 nm and sufficient ionic conductivity of 1.54 mS/cm at 25 °C. In addition, the ASSB cell consisting of the cathode electrode with Li6PS5Cl synthesized by the SEB exhibited a high capacity of 176 mAh/g at 0.1 C (55 °C) owing to the improved contact between the electrode and solid electrolyte. In particular, the rate capability of the cell is superior to that of a cell with Li6PS5Cl prepared by ball milling. [ABSTRACT FROM AUTHOR]
