| 英文摘要 | Novel nanostructured silicon composites, si/poly(3,4-ethylenedioxythiophene) nanowire network (si/pnw) and si/(s-doped-carbon nanowire network) (si/s-cnw), are prepared by a soft-template polymerization of 3,4-ethylenedioxythiophene (edot) using sodium dodecyl sulfate (sds) as surfactant with the presence of si nanoparticles and a subsequent carbonization of si/pnw, respectively. the presence of si nanoparticles in the soft-template polymerization of edot plays a critical role in the formation of pedot nanowire network instead of 1d nanowire. after the carbonization of pedot, the s-doped-carbon nanowire network matrix shows higher electrical conductivity than pnw counterpart, which facilitates to construct robust conductive bridges between si nanoparticles and provide large electrode/electrolyte interfaces for rapid charge transfer reactions. thus, si/s-cnw composite exhibits excellent cycling stability and rate capability as anode material, retaining a specific capacity of 820 mah g(-1) after 400 cycles with a very small capacity fade of 0.09% per cycle.
