Abstract. A single-step high-energy ball milling process was used for the synthesis of a Li 5.3 PS 4.3 ClBr 0.7 glass ceramic. This material exhibits a Li + conductivity of 5.2 mS cm −1, the highest value reported so far at room temperature for a Li + solid electrolyte pellet prepared without any annealing step. We demonstrate the utilization of this electrolyte in …
