The reference synthesis of Li 3 PS 4 was performed within the high energy ball mill considering a rotational speed of 800 rpm, 10 mm media size and media filling ratio. Due to the active cooling of the grinding jars, the synthesis was performed as a continuous process without the oftenreported process discontinuities caused by cooling breaks.
