a b s t r a c t 4 V-class olivine C-LiMn 1-x Fe x PO 4 (x = 0 and 0.15) are synthesized by ultrasonic pyrolysis followed by ball milling with AB carbon to evaluate the doping effect of iron. The C-LiMn 0.85 Fe 0.15 PO 4 shows excellent rate capability having discharge capacity of 150 mAh g -1 at 0.5
To improve the performance of LiFePO 4 , single phase Li 1-x Na x FePO 4 /C (x = 0, 0.01, 0.03, 0.05) samples are synthesized by in situ polymerization restriction-carbonthermal reduction method. The effects of Na doping are studied by X-ray diffraction (XRD), scanning electron microscopy (SEM), tra
