چکیده انگلیسی
Mesoporous FePO4 could deliver enhanced specific capacity of 160 mAh g−1 at first discharge process, 90% of theoretical capacity of pure FePO4, and 135 mAh g−1 in the following cycles at 0.1 C rate. At 1 and 3 C rates, the capacities are 110 and 85 mAh g−1, respectively, which is much higher than that of previously reported for modified FePO4 materials. Electrochemical impedance spectroscopy (EIS) tests proved that mesoporous structure in FePO4 materials enhanced the lithium ion intercalation/deintercalation kinetics as indicated by smaller charge transfer resistance (Rct) of these materials. These results revealed that this mesoporous electrode material can be a potential candidate for high-power energy conversion devices.
