Abstract

We report on the synthesis and characterization of two solid electrolytes, Li $_{10}$ SnP $_2$ S $_{12}$ and Li $_{11}$ Si $_2$ PS $_{12}$ , which are based exclusively on abundant elements. Both compounds feature extremely high Li ion diffusivities, with the Si-based material even surpassing the present record holder, the related electrolyte Li $_{10}$ GeP $_2$ S $_{12}$ . The structure and dynamics were studied with multiple complementary techniques and the macroscopic diffusion could be traced back to fast Li ion hopping in the crystalline lattice.
