A　mesoporous　LiFe0.99Mo0.01PO4/C　composite　was　synthesized　by　the　sol-gel　method　using　(NH4)(2)MoO4　as　a　doping　starting　material.　The　formation　of　conductive　carbon,　metal　doping　and　mesopores　was　achieved　simultaneously　in　the　prepared　material.　The　characterizations　of　crystal　structures　and　microstructures　were　investigated　using　X-ray　diffraction　(XRD),　scanning　electron　microscopy　(SEM),　transmission　electron　microscopy　(TEM),　extended　X-ray-absorption　fine-structure　(EXAFS)　and　X-ray-absorption　near-structure　spectroscopy　(XANES),　while　the　surface　area　was　determined　using　N-2　adsorption　techniques.　Cyclic　voltammetry　(CV)　and　charge-discharge　cycling　performance　were　used　to　characterize　its　electrochemical　properties.　The　sample　possessed　uniformly　distributed　mesopores　with　an　average　pore　size　of　4　nm,　and　the　specific　surface　area　was　about　69.368　m(2)/g.　The　results　show　that　the　reversible　capacity　of　mesoporous　LiFe0.99Mo0.01PO4/C　is　about　160　mAh/g　at　0.1C,　135　mAh/g　at　1C　and　90　mAh/g　at　5C,　respectively.　The　capacity　fading　is　neglectable.
