Advanced Energy Materials, EarlyView.A superionic conductivity of 42 mS cm−1 at 298 K is reported for Li2.55Sc0.15Sb, which exceeds the highest ionic conductivity reported for a solid Li‐ion conductor to date by 10 mS cm−1. In the series Li3−3xScxSb (0 < x ≤ 0.15), the gradual incorporation of Sc facilitates vacancy formation, converting pristine Li3Sb from an electrical to an ionic ...
