中文摘要	lifepo4/c composite nanofibers were synthesized by calcination of the [lioh + fe(no3)(3) + h3po4]/pvp electrospun nanofibers. polyvinyl pyrrolidone (pvp) was used as the electrospinning template and carbon source. during the calcination [lioh + fe(no3)(3) + h3po4] were transformed to lifepo4 and pvp was decomposed into carbon. the morphology and properties of the as-prepared samples were characterized by x-ray diffraction, scanning electron microscopy, transmission electron microscopy, brunauer-emmett-teller (bet) specific surface area analysis, electrochemical impedance spectroscopy and galvanostatic charge-discharge measurements. the results indicate that the mean diameter of as-prepared lifepo4/c composite nanofibers is 179.08 +/- a 29.66 nm and the bet specific surface area is 66.59 m(2) g(-1). the addition of carbon does not affect the structure of lifepo4, but improves its electrochemical performances. at the current density of 0.2 c, the initial discharge capacity of lifepo4/c electrode is 133.6 mah g(-1) and there is no obvious capacity fading after 100 cycles. the formation mechanism of the lifepo4/c composite nanofibers was also proposed.
