Carbon nanofibers (CNFs) are long, fibrous carbon layers of a platelet type - perpendicularly arranged individual layers to the fiber axis or of herringbone type - nested inside one another at an angle. The arrangement is determined depending on the catalyst used Carbon nanofibers (CNFs) are in a class of one-dimensional carbonaceous materials with exceptional electronic conductivity, which made them a perfect use as conductive additives in electrode materials for lithium-ion batteries and sodium-ion batteries.
When Carbon nanofibers (CNFs) are used explicitly as anode materials for production of numerous intercalation sites, they show excellent performance of sodium and lithium storage. For non-carbon electrodes of lithium-ion & sodium-ion, Carbon nanofibers (CNFs) can function as electron conducting and porous substrates enhancing the overall electronic & ionic conductivity alongside with stabilization of the electrode structures during cycling, causing the improvement of the non-carbon anode and cathode materials’ electrochemical performance.
Since Carbon nanofibers (CNFs) do have irregular surface structure, with many corners and edges, it makes them an ideal material for fast adsorption/desorption processes. Carbon nanofibers (CNFs) are also often used as a nanostructured catalyst and catalyst carrier. Especially due to the combination of catalytic activity with their inherent excellent electrical and thermal conductivity, they open attractive possibilities for use in catalytic processes. Also the platelet type Carbon nanofibers (CNFs) are used in self-lubricating materials.
Carbon nanofibers (CNFs) are produced catalytically in the CVD process. Carbon nanofibers (CNFs) undergo the process of synthesis by co-catalyst deoxidization process by a reaction between C2H5OC2H5, Zn and Fe powder at 650 °C for 10 h. X-ray diffraction, Raman spectroscopy, and high-resolution transmission electron microscopy indicate that as-prepared CNFs possess low graphitic crystallinity. The resultant CNFs as electrode shows capacity of ∼220 mAh/g and high reversibility with little hysteresis in the insertion/deintercalation reactions of lithium-ion.
While having similar ratio of length to diameter (aspect ratio) to that of the carbon nanotubes still, they are significantly larger, normally having a diameter ranging between 150–300 nm.In case metallic intermediate layers are applied between the graphene layers the material shows an improvement in the binding of Carbon Nanofibers (CNFs) to ceramic and metallic matrices. This modification makes the nanofibers suitable for the use in composite materials.
