Improving the electrochemical performance of cathode composites using different sized solid electrolytes for all solid-state lithium batteries.

We studied the efficiency of different particle-sized sulfide solid electrolyte-based cathode composites. First, we prepared the LiPSI solid electrolytes with different particle sizes through a high energy ball milling process and solution method. The structural details of the prepared solid electrolytes were studied by powder X-ray diffraction.
