“…High‐resolution C1s, N1s, and O1s XPS spectra for the prepared N‐doped carbons are shown in Figure and Figure S4. Four binding environments with binding energies at around 398.5, 400.4, 401.3, and 403.3 eV were found, ascribed to pyridinic, pyrrolic, graphitic and pyridine‐N‐oxide, respectively (Figure ) ,. High‐resolution C1s and O1s XPS spectra for all carbons demonstrating the existence of C and O atoms with different coordination environments are presented in Figure S4.…”

The conversion of bio‐waste into useful porous carbons constitutes a very attractive approach to contribute to the development of sustainable energy economy, even more as they can be used in energy storage devices. Here we report the synthesis of N‐doped carbons from hydrothermal carbonization of macroalgae, Enteromorpha prolifera (EP), followed by a mild KOH activation step. The obtained N‐doped carbons exhibited surface areas of up to ∼2000 m2/g with N‐loadings varied in the range of 1.4∼2.9 at %. By modifying activation temperature, we were able to tune the surface chemistry and porosity, achieving excellent control of their properties. The specific capacitance reached values of up to 200 F/g at 1 A/g in 6 M KOH for the sample obtained at activation temperature of 700 °C (AHC‐700). The symmetric supercapacitor using the sample activated at 800 °C (AHC‐800) as electrodes exhibited the highest cycling stability of the samples studied in this work, with capacitance retention of up to 96 % at 10 A/g, even after 10,000 cycles, constituting the highest reported for biomass‐derived carbon electrodes. These results show the great potential of N‐doped carbons as electrodes for supercapacitors and confirm the excellent electrochemical properties of biomass‐derived carbons in energy storage technologies.

“…The average CE of the NC/NF samples is about 100 % from the 10th cycle to the1000th cycle. As shown in Figure d, the impressive rate performance of NC/NF‐800 outperforms many reported nitrogen‐doping carbon anodes for SIBs …”

“…The crystalline domain relates to the flocculent structure on the surface of carbon spheres in SEM. The interlayer distances of the crystalline domain were measured using the DigitalMicrograph software as 0.45 nm, 0.49 nm, and 0.41 nm, respectively, which shows the obviously enlarged interlayer distances than C/NF (0.38 nm, Figure S1d) and most of the heteroatom‐doped carbon materials reported so far . More significantly, this enlarged interlayer distance is beneficial to conquer the energy barrier of sodium‐ion intercalation/deintercalation, which can be associated with the specific configurations of Nitrogen‐doping.…”

“…The R s reflects the electronic conductivity of the system, relating to the high frequency intercept with the X‐axis, and includes the inherent resistance of the anode materials and the electrolyte, along with the contact resistance at the interface between the anode materials and the Ni foam. Z w relates to the diffusion of the Na + and is corresponds to a sloping line at low frequencies . Before cycles, NC/NF‐800 has the smallest R ct and R s than NC/NF‐700, NC/NF‐900, and C/NF‐800.…”

Nitrogen‐doped hard carbon on Ni foam (NC/NF) with numerous active sites, expanded interlayer distance (0.49 nm), and highly ordered pseudo‐graphic structure is synthesized by a melamine‐assisted hydrothermal pretreatment and subsequent pyrolysis procedure. The high content configurations of pyrrolic‐nitrogen and pyridinic‐nitrogen in NC/NF could provide abundant active sites and defects for efficient Na+ adsorption/desorption and improved transport kinetics. The obvious flocculent structures on carbon surface, corresponding to the highly ordered pseudo‐graphic structure, could enhance the transport kinetics for electrons. The strong electrostatic repulsion of pyrrolic‐nitrogen could expand interlayer distance, facilitating Na+ insertion/extraction process. The balance between high nitrogen content and sufficient graphitization degree comes into strong carbon frameworks with enhanced structural stability and electronic conductivity. When served as free‐standing anodes for sodium‐ion batteries (SIBs), NC/NF presents high rate capability of 128.5 mAh g−1 at 10 A g−1, and excellent cycling stability of 225.4 mAh g−1 after 1000 cycles under high current density of 5 A g−1. These results demonstrate a new light to prepare advanced anodes for SIBs.

“…With the increase in current density, the B‐SZVO electrode delivers average reversible discharge capacities of 933.8, 847.9, 780.8, and 664.1 mAh g −1 , respectively, whereas the S‐SZVO electrode delivers decreased average reversible discharge capacities of 592.2, 443.4, 381.1, and 311.6 mAh g −1 , respectively. The better electrochemical reversibility and rate capability of B‐SZVO may be attributed to the N‐doped carbon which improved the conductivity and facilitated rate performance …”

Plant oil–inspired 3D flower‐like Zn3V3O8 nanospheres coupled with nitrogen doped (N‐doped) carbon synthesized via the microemulsion/calcination strategy are used as anodes for lithium‐/sodium‐ion batteries (LIBs/SIBs). The synergistic interaction between the unique 3D flower‐like structure and the existence of N‐doped carbon can provide enough space to buffer volume expansion during the Li+/Na+ intake/outlet process and enhance conductivity, respectively. Thus, the material delivers progressive electrochemical performance. Specifically, the Zn3V3O8 nanospheres exhibit a reversible specific capacity of 1140.6 mAh g−1 after 200 cycles for LIBs and 113.0 mAh g−1 after 400 cycles for SIBs at a current density of 200 mA g−1. Furthermore, the Zn3V3O8 nanospheres electrode owns rate capability for LIBs such as 933.8, 847.9, 780.8, and 664.1 mAh g−1 at elevated current densities of 200, 400, 800, and 1600 mAh g−1, respectively. In addition, it delivers reversible capacities of 207.5, 119.2, 74.1, and 42.7 mAh g−1 at 100, 200, 500, 1000, and 2000 mA g−1 for SIBs, respectively.
