Abstract
- Abstract: LiFePO4/carbon composite was synthesized at 600°C for 4h in an Ar atmosphere by a stearic acid assisted rheological phase method using amorphous nano-FePO4 as the iron source. XRD, SEM and TEM observations show that the LiFePO4/carbon composite has good crystallinity, ultrafine and well-dispersed particles of 60–150nm size and in situ carbon coated on the surface of LiFePO4 crystallites. The synthesized LiFePO4/carbon composite shows a high discharge capacity of 160mAhg−1 and 155mAhg−1 at rates of 0.5C and 1C, respectively. Even at a high current density of 30C, the material still presents a discharge capacity of 93mAhg−1 and exhibits an excellent cycling performance. [Copyright &y& Elsevier]
