Fabricating titanium dioxide/N-doped carbon nanofibers as advanced interlayer for improving cycling reversibility of lithium-sulfur batteries
文献摘要:
"Shuttle effect"is detrimental for maintaining the high capacity and cycling reversibility of lithium-sulfur batteries(LSBs).To inhibit polysulfide migration,N-doped carbon nanofibers(N-CNFs)membrane com-prising TiO2 nanoparticles(TiO2/N-CNFs)is fabricated using an electrospinning-calcination method and further applied as interlayer in LSBs.The TiO2/N-CNFs interlayer helps the battery to deliver a high speci-fic capacity of 1155.2 mA·h·g-1 at 0.2 C with high Coulombic efficiency,good rate capability and stability.When cycling at 0.5 C,a capacity retention rate of 62.4%is achieved over 300 cycles,which is higher than that of CNFs and TiO2/CNFs counterparts.The excellent performance should mainly be attributed to the alleviated"shuttle effect"deriving from high polysulfide trapping ability of TiO2 nanoparticles and N het-eroatoms in interwoven CNFs.
