Preparation of LiFePO4/C via high-temperature ball-milling
The prepared precursors were separately poured into a high-temperature ball mill, with the mass ratio of ball to powder was 15:1. The process was preheated ball-milling temperature at 300 °C for1 h, after which the ball-milling temperature was increased to target temperature and maintained for a certain time in N 2 atmosphere to prepare LiFePO 4 /C samples.
