Lithium Superionic Conduction in BH₄ -Substituted Thiophosphate Solid Electrolytes.

ABSTRACT: Compared with conventional liquid electrolytes, solid electrolytes can better improve the safety properties and achieve high-energy-density Li-ion batteries. Sulfide-based solid electrolytes have attracted significant attention owing to their high ionic conductivities, which are comparable to those of their liquid counterparts. Among them, Li thiophosphates, including Li-argyrodites, are widely studied. In this study, Li thiophosphate solid electrolytes containing BH₄ ^- anions are prepared via a simple and fast milling method even without heat treatment. The synthesized materials exhibit a high ionic conductivity of up to 11 mS cm^-1 at 25 °C, which is much higher than reported values. To elucidate the mechanism behind, the thiophosphate local structure, who
