Abstract

One of the most common problems with sulfide solid-state electrolytes is weak water stability. We report a re-sintering method to recover the ionic conductivity of argyrodite Li_5.4PS_4.4Cl_1.6 solid-state electrolyte, which has been exposed to moisture for 10 h, from 1.06 to 6.97 mS cm⁻¹.
