“…Carbon nanofibers (CNFs) have achieved a prominent relevance in the last decade due to their excellent mechanical properties, high electrical and thermal conductivities as well as mesoporosity, making them promising materials for an extensive range of applications such as energy storage [1][2][3][4], composites [5], catalysts [6,7] or adsorbents [8,9], among others. CNFs are graphitic fibers made of stacks of graphene layers aligned perpendicular, tilted or parallel to the fiber axis, thus resulting in different microstructures [10].…”

Carbon nanofibers with different microstructure and elemental composition that were produced in the catalytic decomposition of synthetic biogas mixtures, in a rotary-bed reactor using nickel and nickel-cobalt catalysts at 600 ºC and 700 ºC, were heat treated in the temperature interval 2600-2800 ºC to explore their ability to graphitize. The influence of treatment temperature as well as carbon nanofibers composition, particularly metallic species, on the structural and textural properties of the materials prepared is discussed. Graphitic nanomaterials with great development of the three-dimensional structure (d 002 ~ 0.3360 nm, L c ~ 48 nm, L a ~ > 100 nm) and low porosity (S BET ~ 20 m 2 g -1 ) have been achieved. Because of the catalytic effect of silicon in the presence of inherent nickel and cobalt metals, more structurally ordered materials were obtained from the carbon nanofibers by adding silica. Based on the results of this work, the utilization of biogasderived carbon nanofibers for the production of synthetic nanographite to be used in different applications, such as electrode material in energy storage devices in which both high degree of graphitic order and small surface area are required, appears feasible.

“…Impressive advancements have been achieved by integrating high-capacity active materials with constraining matrix, such as Sony's Nexelion batteries which integrate tin-cobalt alloy with graphite and Mitsui mining's SILX Ò batteries which employ copper-coated cerium-tin alloy [5]. Recently, carbon nanofibers are gaining attention as an effective carbon matrix to encapsulate active materials [6][7][8][9][10][11]. Comparing to other matrix materials, carbon nanofibers can not only accommodate the dramatic volumetric expansion of active materials during lithiation/delithiation [12,13], but also maximize the capacity potential of active materials by preventing the nanoparticle pulverization or the loss of electric contact between active substances and the current collector [14].…”

Carbon nanofibers, due to their high electric conductivity and excellent mechanical strength, have been studied and applied in areas such as energy storage, tissue engineering, filtration, and catalysis. So far, carbon nanofibers have been mainly produced by electrospinning and subsequent heat treatments. However, the great difficulty of carbon nanofibers to be scaled up through electrospinning confines the productivity and practical application of this extensively investigated material category. Recently, centrifugal spinning has drawn attention due to its high production rate (500 times faster than traditional electrospinning), simple set-up, and ease of scaling-up. Herein, tin-containing carbon nanofibers were prepared by facile centrifugal spinning from tin chloridepolyacrylonitrile precursor solutions and subsequent thermal treatments. Polymer-salt-solvent relations and resultant rheological effects upon solution properties and fiber structures were discussed, and the performance of centrifugally spun tin-containing carbon nanofibers as anode material for lithium-ion batteries was evaluated. An excellent reversible capacity of 607 mAh g -1 was achieved at the initial cycle and a relatively high specific capacity of 430 mAh g -1 was maintained after 100 cycles. It is, therefore, demonstrated that centrifugal-spun tincontaining carbon nanofibers are promising anode material for lithium-ion batteries, and centrifugal spinning, as a nanofiber fabrication alternative to electrospinning, shows great potential in large-scale nanofiber production.

A new route consisting of simultaneous centrifugal spinning and solution blowing to form polymer nanofibers is reported. The fiber diameter (60–1000 nm) is shown to be a function of polymer concentration, rotational speed, and working pressure of the processing system. The fiber length is dependent on the rotational speed. The process can deliver 6 kg of fiber per hour and therefore offers mass production capabilities compared with other established polymer nanofiber generation methods such as electrospinning, centrifugal spinning, and blowing.
