“…As shown in Figure 9 , the Na-ion storage performance of C400, obtained by the thermal treatment of the biomass at 400 °C (below the critical temperature of 445 °C), is lower than those of C500 and C600, obtained at 500 and 600 °C, respectively. This improvement can be related to the development of disordered graphitic structure at greater temperatures, providing further active sites to accommodate Na-ions [ 35 ]. Moreover, as can be observed in Figure 9 a, the specific capacity of C600B is greater than that of other samples, which is related to the higher carbon purity and lower particles sizes in this sample.…”

Hard carbon materials are considered to be the most practical anode materials for sodium ion batteries because of the rich availability of their resources and potentially low cost. Here, the conversion of corn leaf biomass, a largely available agricultural waste, into carbonaceous materials for Na-ion storage application is reported. Thermal analysis investigation determines the presence of exothermic events occurring during the thermal treatment of the biomass. Accordingly, various temperatures of 400, 500, and 600 °C are selected to perform carbonization treatment trials, leading to the formation of various biocarbons. The materials obtained are characterized by a combination of methods, including X-ray diffraction, electron microscopy, surface evaluation, Raman spectroscopy, and electrochemical characterizations. The Na-ion storage performances of these materials are investigated using water-soluble carboxymethyl cellulose binder, highlighting the influence of the carbonization temperature on the electrochemical performance of biocarbons. Moreover, the influence of post-mechanochemical treatment on the Na-ion storage performance of biocarbons is studied through kinetic evaluations. It is confirmed that reducing the particle sizes and increasing the carbon purity of biocarbons and the formation of gel polymeric networks would improve the Na-ion storage capacity, as well as the pseudocapacitive contribution to the total current. At a high-current density of 500 mA g−1, a specific Na-ion storage capacity of 134 mAh g−1 is recorded on the biocarbon prepared at 600 °C, followed by ball-milling and washing treatment, exhibiting a reduced charge transfer resistance of 49 Ω and an improved Na-ion diffusion coefficient of 4.8 × 10−19 cm2 s−1. This article proposes a simple and effective technique for the preparation of low-cost biocarbons to be used as the anode of Na-ion batteries.

“…With an increase in the pyrolysis temperature, the ICE increases as a result of the decreased amount of defects, and thus lowers the irreversible capacity. 42–86 In summary, high-temperature pyrolysis treatment is a necessary step to ensure the graphitization structure of the final products. However, different pre-treatments are applied to achieve desirable performance according to different precursors.…”

“…The Na + intercalation behavior on the sloping part was further emphasized by Tonnoir et al. [ 29 ] and in a dilatometric study [ 30 ] where a significant change in electrode thickness was measured on the sloping part for sodiation process. In addition, as a result of the mechano‐electrochemical study by Yang et al., [ 31 ] the adsorption‐intercalation behavior was assigned to the sloping region.…”

Here, the sodium storage mechanism in commercial grade hard carbon with a low surface area is comprehensively investigated using electrochemical impedance spectroscopy (EIS), the galvanostatic intermittent titration technique, and in situ Raman spectroscopy for fresh and cycled electrodes. The reversible shift of the carbon G‐band peak on Raman spectra and substantial change of the charge‐transfer resistance in the sloping region of the voltage profile indicates the intercalation of sodium ions into hard carbon, whereas the low‐voltage plateau is associated with the pore‐filling process. In situ Raman analysis at low frequencies reveals that the pore filling is progressed via formation of small sodium clusters in closed pores. Prolonged cycling demonstrates that intercalation is stable and consistent throughout multiple charge–discharge cycles. The transition from intercalation to pore filling strongly affects the diffusion behavior, leading to considerably slower diffusivity at low voltage. The EIS effectively differentiates the contribution of adsorption to charge storage. The gradual growth of the solid‐electrolyte interphase layer affects the rise of the interfacial resistance as cycling progresses. In combination with the slower diffusivity, the low‐voltage plateau region strictly impedes fast de/sodiation and eventually causes capacity fade.
