“…The NCL@GF posses both high discharge capacity and excellent stable performance, which contributes to the unique structure of the NCL@GF.F irst, N-doping in the carbon framework can supply abundant sites for sodium storage and enhance the electrode kinetics. [26,[28][29][30][31] Second, the porousc arbon layers on the graphene framework can improve the specificc apacity by surface adsorption and faradic reaction, while the hierarchical porousc hannels can provide facilitate pathways for electrolyte and improvet he rate performance. [12,18,23,[32][33][34][35] Third, the graphene frameworks effectively expose the active surface to the electrolyte but also offer multidimensional electron transport pathway and shorten ion diffusion distance to promote the electrochemical reaction throughout the entire electrode.…”

Bacterial cellulose-derived carbon nanofibers as both anode and cathode for hybrid sodium ion capacitor

“…[14][15][16] Our previous work has demonstrated that N,P and N,O dual-doped carbon nanomaterials showed signicantly enhanced Na storage performance. 17,18 Due to the working principle of cathode materials in HICs that is the same as that of EDLCs, the main factors that affect the capacitance performance are the specic surface and pore size distribution of the carbon materials. The high specic surface area and suitable pore size distribution are advantageous for achieving high specic capacitance and excellent rate performance.…”

From Jackfruit Rags to Hierarchical Porous N-Doped Carbon: A High-Performance Anode Material for Sodium-Ion Batteries

“…In addition, their high electrical conductivity and large electrolyte/electrode contact area are favorable to the reversible insertion and extraction of Na + , resulting in excellent and stable electrochemical performance [23]. Many types of biomass such as bamboo [24], water hyacinths [25], waste tea [26], corn stalk [27], wood [28,29], lotus [30], kelp [31], and human hair [32] have been investigated as a precursor for producing porous carbon materials for various energy storage devices; however, it is still a challenge to prepare high-performance porous carbon from a cost-efficient resource.…”
