Abstract

We report a “solo-solvent de novo liquid-phase” method of synthesizing a highly-favored sulfide electrolyte (Li₆PS₅Cl) for developing all-solid-state lithium batteries. The key chemistry for such a successful method is that tetrahydropyrrole enables in situ synthesis of the critical precursor Li₂S from cheap and air-stable precursors of lithium chloride and sodium sulfide.
