The prepared and electrochemical property of Mg-doped LiMn
After ball milling for 1 h by ball mill, the precursor slurry with a solids content of 35 wt.% was spray-dried in a pressure spray dryer at a speed of 20 mL·min −1. The inlet temperature was 230–280 ℃, and the outlet temperature was 100–110 ℃. The nozzle diameter is 1 mm and the inlet pressure is 0.4 MPa.
