Composite Li(0.99)Mo(0.01)FePO4/C cathode materials were prepared by an easy solution method followed by heat-treating at various temperatures. XRD, SEM, TGA/DTA, EA, CV, XPS and charge-discharge cycles were used to evaluate the Li0.99Mo0.01FePO4/C Composite powders. The results indicate that mix-doping method does not affect the olivine structure of the cathode but considerably improves its capacity delivery and cycle performance. Among the prepared cathode materials, the sample heat-treated at 700 degrees C for 12 It shows best electrochemical performances. It shows initial specific discharge capacities of 161 and 124 mAh g(-1) with C rates of 0.2C and 2C, respectively, which is ascribed to the enhancement of the electronic conductivity by ion doping and carbon coating.
