“…The signal of N 1s could be obviously resolved into two peaks with binding energy of 398.28 and 399.86 eV (Fig. 3c), corresponding to pyridinic nitrogen and pyrrolic nitrogen [33,34], further confirming that the existence of nitrogen in MoO 2 @NC NFs. It is well-known that the nitrogen-doped carbon material can enhance the electrical conductivity and accelerate the reaction speed of the carbonaceous composites [35][36][37].…”

MoO 2 @N-doped C nanofibers (MoO 2 @NC NFs) were synthesized by electrospinning with polyacrylonitrile as carbon source. The in situ formed MoO 2 nanocrystals are completely embedded in the carbon nanofibers, which can not only accelerate ion transition, but also act as a buffer to avoid the mechanical degradation of active material due to the volume changes during charge/discharge cycling. When used as the anode material for both Li/Na-ion batteries, the as-synthesized MoO 2 @NC NFs displayed excellent Li + /Na + storage properties. As the anode for Li-ion battery, the MoO 2 @NC NFs display a high discharge capacity of 930 mA h g −1 at a current density of 200 mA g −1 for 100 cycles, and 720 mA h g −1 at a current density of 1 A g −1 for 600 cycles. Moreover, the discharge capacity of 350 mA h g −1 could be realized at a current density of 100 mA g −1 for 200 cycles for Na-ion battery.

“…Because N doping can enhance the electronic conductivity and wettability, while O, B, S or P-doping can provide the pseudo-capacitance, enlarge the carbon interlayer distance and increase additional active sites, N, O co-doping [34,122,123,129,138], N, B co-doping [35,147], N, S codoping [81,92,146,148] and N, P co-doping [39,99,149] have been designed to further improve the electrochemical performances of biomass-derived carbon materials. For instance, Sun et al [147] reported a separated N, B co-doped porous graphitic carbon from nitrogencontaining chitosan through coordinating boric acid and Fe catalyst, and followed by ZnCl 2 -activation process.…”

“…Accordingly, among various types of carbon materials, hard carbon-based materials are considered a promising anode candidate for sodiumion batteries, owing to their large interlayer distance, non-ordered structure, high reversible capacity, low average potential, long cycling stability and low cost. Hard carbon materials are commonly produced from the pyrolysis of polymers, meanwhile they can also be derived from a variety of biomass precursors, such as sucrose [37], glucose [39], lotus petioles [145], coconut oil [21], ramie fibers and corncobs [57], corn cobs [215], horn comb [216], bacterial cellulose [70], oatmeal [22], maize [217], okara [96], dandelion [76], grass [218], black fungus [219]. However, hard carbon anode materials exhibited a low initial Coulombic efficiency due to the formation of solid electrolyte interface (SEI) layer.…”

“…The introduction of S atom into carbon structure can increase carbon interlayer distance, which not only provides the amount of active sites to store sodium-ions, but also synchronously accelerates sodium-ion insertion/de-insertion, further enhancing electrode kinetics. Moreover, the common nitrogen and phosphorous doping/co-doping can also play the same role [39]. The large interlayer distance after heteroatom doping facilitates the transport and storage of sodiumions inside the biomass-derived carbon materials, which results in the high rate performance for sodium-ion batteries.…”

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.
