Abstract
A convenient one-pot method, called high-temperature high-energy mechanical force (HTHEMF), was successfully developed for the preparation of LiFePO4/C composites. Upon the combination of high-temperature with high-energy mechanical force, the whole synthesis process of this method is very simple and only involves two steps, the precursor preparation and the calcination step. The results of XRD, SEM, BET and electrochemical performance tests indicated that after calcination at 600 °C for 9 h, the LiFePO4/C composites have the best properties. The discharge capacity of the composites was 150.3mA h g-1 at 0.1 C. After 30 cycles test, the reversible capacity was 147 mA h g-1 and the retention ratio to the initial capacity was 97.8%. The results indicated that LiFePO4/C composites with good properties can be obtained by one-pot HTHEMF method.
