英文摘要 | the lifepo4/c composite is prepared by heating the mixture of resorcinol-formaldehyde gel and fepo4, synthesized by an in situ polymerization restriction method, and lithium acetate dihydrate in the atmosphere of nitrogen. the physical and electrochemical properties of the lifepo4/c composite are investigated by x-ray diffraction, raman spectroscopy, thermogravimetric analysis, scanning electron microscopy, transmission electron microscopy and electrochemical measurements. the discharge capacity of lifepo4 is as high as 155.6 ma h g(-1) in the first cycle at 0.5c, and it could remain 144.0 ma h g(-1) after 50 cycles. even at the high rates of 10c, 20c and 50c, the initial discharge capacities of the electrodes exhibit 115.6 ma h g(-1), 84.5 ma h g(-1) and 67.8 ma h g(-1), and the electrodes deliver capacity retention of 89.5%, 90.9% and 85.7% after 1000 cycles, respectively. the outstanding electrochemical performance could be attributed to the small particle size and good electronic conductivity of the composite.
