Local structure of amorphous sulfur in carbon-sulfur composites for all-solid-state lithium-sulfur batteries.

All-solid-state (ASS) batteries are a promising solution to achieve carbon neutrality. ASS lithium-sulfur (Li-S) batteries stand out due to their improved safety, achieved by replacing organic solvents, which are prone to leakage and fire, with solid electrolytes. In addition, these batteries offer the benefits of higher capacity and the absence of rare metals.
