N-Doped Carbon Nanofibers Encapsulating CoO@Co9S8 Nanoparticles:Preparation from S-Rich Co32 Coordination Cluster Precursors by Electrospinning and Application for Superior Li-ion Storage
文献摘要：
Thiacalixarene-supported Co32 nanoclusters encapsulated in polyacrylonitrile nanofibers(Co32@PAN-NFs)by electrospin-ning have been utilized as precursors to fabricate N-doped CoO@Co9S8 carbon nanofibers(CoO@Co9S8@CNFs)for superior Li-ion storage.The S-rich Co32 clusters capped by organic sheets af-forded the well dispersed cobalt oxide/sulfide nanoparticles embed-ded in carbon nanofiber composites by direct calcination.The N-doped CoO@Co9S8@CNFs nanocomposites have been utilized as anode materials for lithium ion battery with the reversible capabili-ties being of 1051.8,967.6,894.7,782.7,669.5 and 525.4 mA·h/g at 0.1,0.2,0.5,1,2 and 3 A/g,respectively.The CoO@Co9S8@CNFs also showed a relatively high stable capacity of 551.7 mA·h/g at the current density of 1 A/g after 200 cycles of rate experiments.The as-obtained N-doped CoO@Co9S8@CNFs nanocomposites exhibited superior reversible capacity,rate performance,Coulomb efficiency(74.5％vs.63.9％)and cyclic stability comparing with the CoO@Co9S8@C derived from simple annealing of Co32 templates.
