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 an all-solid-state battery ...

In this paper, the milling parameters of high energy ball mill (Fritsch Pulverisette 7) like vial geometry, number and size of balls and speed of the mill were modelled and discussed. Simulations through discrete element method (DEM) provide correlation between the milling parameters. A mathematical model is used to improve and develop this process.
