| Özet |
| Co3O4/carbon composite nanofibers were prepared by a combination of electrospinning and carbonization methods using 10 - 30 nm and 30 - 50 nm Co3O4 nanoparticles, respectively, and their potential use as the anode material in rechargeable lithium-ion batteries was investigated. The composite Co3O4/carbon nanofiber electrode containing 30 - 50 nm Co3O4 nanoparticles showed large reversible capacities and good cycleability with charge capacities of 677 and 545 mAh g(-1) at the second and twentieth cycles, respectively. In contrast, the composite Co3O4/carbon nanofiber electrode containing 10 - 30 nm Co3O4 nanoparticles showed fast capacity fading during cycling due to severe nanoparticle aggregation. Results suggested that the good electrochemical performance of Co3O4/carbon nanofiber electrode containing 30 - 50 nm Co3O4 nanoparticles was ascribed to the combination of the properties of both Co3O4 nanoparticles (large Li storage capability) and carbon nanofiber matrix (long cycle life), and therefore this electrode material could be potentially used in high-energy rechargeable lithium-ion batteries. |
