Nano-rod Mn-doped carbon coating LiFePO4 composites have been synthesized by a samplesolvothermal process coupled with calcination, which shows an excellent performance at high ratecondition. The morphology and microstructure of the composites were evidenced by scanning electronmicroscopy (SEM), X-ray diffraction (XRD) and transmission electron microscopy (TEM). Theelectrochemical properties were evaluated by constant current charge/discharge test. Mn-dopingmagnified the interplanar spacing, providing a smoother aisle for ionic transport, it is beneficial toimprove electrochemical properties at high rate. The stability was enhanced as well combined withcarbon coating. In electrochemical measurement of the specific charge capacity, rate capacity andcycling stability, the obtained composite rod-like materials offer remarkably promising results forapplication, the initial discharge capacity is 160 mAh·g-1at 0.2 C and 120 mAh·g-1at 10 C, the capacityretention ratio is 94% at 0.2 C and 93% at 10 C after 50 charge-discharge cycles.
