Realizing high-capacity all-solid-state lithium-sulfur batteries using a low-density inorganic solid-state electrolyte.

ABSTRACT: Lithium-sulfur all-solid-state batteries using inorganic solid-state electrolytes are considered promising electrochemical energy storage technologies. However, developing positive electrodes with high sulfur content, adequate sulfur utilization, and high mass loading is challenging. Here, to address these concerns, we propose using a liquid-phase-synthesized Li₃PS₄-2LiBH₄ glass-ceramic solid electrolyte with a low density (1.491 g cm^-3), small primary particle size (~500 nm) and bulk ionic conductivity of 6.0 mS cm^-1 at 25 °C for fabricating lithium-sulfur all-solid-state batteries. When tested in a Swagelok cell configuration with a Li-In negative electrode and a 60 wt% S positive electrode applying an average stack pressure of ~55 M
