Zusammenfassung:In our work, interface synthesis method was put forward to prepare FePO4 with different morphologies, and the effect of morphology on the preparation and electrochemical performance of LiFePO4/C was investigated. The results showed that the morphology of FePO4 was amorphous and monoclinic at the treatment temperatures of 30 °C and 80 °C, respectively. LiFePO4/C prepared from two crystal precursors were both hemispherical hollow with an olivine crystal structure. LiFePO4/C produced from the monoclinic structured precursor exhibited smaller- sized morphology and better electrochemical performance, and its discharge capacities were 155.9 mA h g−1 and 141.8 mA h g−1 at the rates of 0.1 C and 1 C, respectively. After 150 cycles, its capacity retention was about 97.8 % and 95.1 % at 0.1 C and 1 C, respectively
