“…Figure 8(a) shows the cyclic voltammograms of Cusupported NCNFs electrodes tested at 0.1 mV s −1 . Cu-supported NCNFs electrodes exhibits typical CV curves of carbonaceous materials, which are well consistent with those reported in previous studies [38,39]. In the first lithiation process, an obvious irreversible peak at 0.25 V could be ascribed to the decomposition of electrolyte as well as the formation of SEI layer.…”

Cu-supported nitrogen-doped carbon nanofibers (NCNFs) were fabricated via electrospinning and subsequent activation treatment with poly vinylpyrrolidone as both carbon and nitrogen sources. The NCNFs are firmly adhered to Cu foil without any additional binder and form a hierarchical three-dimensional net structure, which could effectively shorten the diffusion paths for electrons and lithium ions, thus resulting in lower impedance and superior electrochemical properties. Additionally, NCNFs feature a amorphous carbon structure, N-rich carbon lattice and wide pore distribution, not only ensuring fast ions/electrons transport, but also giving rise to the higher energy density. When directly used as a binder-free electrode, NCNFs deliver a high reversible capacity of 617.8 mAh g−1 at 200 mA g−1 after 100 cycles and maintain a superior capacity of 274.1 mAh g−1 at 1.44 A g−1 even after 500 cycles. Besides, the reversible capacity up to 216.5 mAh g−1 can be still obtained at a high current density of 6 A g−1, demonstrating the excellent high-rate cyclability. The facile synthesis approach and superior electrochemical properties make NCNFs electrodes an alternative anode candidate for lithium-ion batteries.

“…The perfect maintenance of NCNFs after cycling is well consistent with their stable cyclability and high capacity retention. In addition, it is obvious that the surface of NCNFs after cycling appears to be rough and dense, which could be reasonably ascribed to the formation of SEI film and some residual electrolytes on the surface [38,44].…”

“…XRD analysis (Figure 6a and Table S2) and Raman spectroscopy ( Figure 6b) were used to characterize the graphitization structure of different electrospun CNFs. Two peaks located at 2θ = 24 • (major) and 43 • (minor) can be indexed to typical crystallographic plane of (002) and (100) graphitic carbon, respectively [37,38]. As shown in Table S2, the graphitic interplanar spacing (d (002) ) of different CNFs ranged from 3.61 to 3.64 Å, the crystallite size (L c ) ranged from 0.94 to 1.02 nm, and the lateral size (L a ) ranged from 2.65 to 3.51 nm.…”

A Feasible Way to Produce Carbon Nanofiber by Electrospinning from Sugarcane Bagasse

Recently, the nanofiber materials derived from natural polymers instead of petroleum-based polymers by electrospinning have aroused a great deal of interests. The lignocellulosic biomass could not be electrospun into nanofiber directly due to its poor solubility. Here, sugarcane bagasse (SCB) was subjected to the homogeneous esterification with different anhydrides, and the corresponding esterified products (SCB-A) were obtained. It was found that the bead-free and uniform nanofibers were obtained via electrospinning even when the mass fraction of acetylated SCB was 70%. According to the thermogravimetric analyses, the addition of SCB-A could improve the thermal stability of the electrospun composite nanofibers. More importantly, in contrast to the pure polyacrylonitrile (PAN) based carbon nanofiber, the SCB-A based carbon nanofibers had higher electrical conductivity and the surface N element content. In addition, the superfine carbon nanofiber mats with minimum average diameter of 117.0 ± 13.7 nm derived from SCB-A were obtained, which results in a larger Brunauer–Emmett–Teller (BET) surface area than pure PAN based carbon nanofiber. These results demonstrated that the combination of the homogeneous esterification and electrospinning could be a feasible and potential way to produce the bio-based carbon nanofibers directly from lignocellulosic without component separation.

“…Moreover, in nature, the biomass material with fibrous structure can be found everywhere, such as flax [55], ramie [56,57], stem bark [58], lotus seedpods [59], bacterial cellulose [24,[60][61][62][63][64], because they usually contain lignin and cellulose. It is wellknown that electrospinning is a powerful and simple technique for fiber production [65]. Therefore, some researchers use lignin as raw material to obtain biomassbased carbon fibers by electrospinning method [66,67].…”

Currently, carbon materials, such as graphene, carbon nanotubes, activated carbon, porous carbon, have been successfully applied in energy storage area by taking advantage of their structural and functional diversity. However, the development of advanced science and technology has spurred demands for green and sustainable energy storage materials. Biomass-derived carbon, as a type of electrode materials, has attracted much attention because of its structural diversities, adjustable physical/chemical properties, environmental friendliness and considerable economic value. Because the nature contributes the biomass with bizarre microstructures, the biomass-derived carbon materials also show naturally structural diversities, such as 0D spherical, 1D fibrous, 2D lamellar and 3D spatial structures. In this review, the structure design of biomass-derived carbon materials for energy storage is presented. The effects of structural diversity, porosity and surface heteroatom doping of biomass-derived carbon materials in supercapacitors, lithium-ion batteries and sodium-ion batteries are discussed in detail. In addition, the new trends and challenges in biomass-derived carbon materials have also been proposed for further rational design of biomass-derived carbon materials for energy storage.
