Abstract Sodium‐ion batteries (NIBs) have gained significant attention in recent years due to the global abundance and cost‐effectiveness of sodium, making them a promising alternative lithium‐based batteries. In this study, nitrogen‐doped graphene oxide powders (NGO) been prepared one step by using chronoamperometric method then used as anode materials for NIBs. The NGO powder surface is covalently doped C−N formation. synthesized had few layers (~3 layers) with nanocrystalline domain size (Lα) ~46 nm, number sp 2 carbon rings was calculated be ~18. initial discharge capacity recorded 199.8 mAh g −1 at 0.1 C rate. Besides, retention long‐term cycling 100 cycles rate 91.78 %. deduced diffusion coefficient from galvanostatic intermittent titration technique (GITT) electrochemical impedance spectroscopy (EIS) measurements NIBs range 10 −11 –10 −12 cm s . performance attributed enhanced d‐spacing up 6.8 °A formation large defects.

Abstract Sodium‐ion batteries (SIBs) are emerging as a potential alternative to traditional lithium‐ion due the abundant sodium resources. Carbon anodes, with their stable structure, wide availability, low cost, excellent conductivity, and tunable morphology pore exhibit outstanding performance in SIBs. This review summarizes research progress of hard carbon anodes SIBs, emphasizing innovative paths advanced performances achieved through multitrack optimization, including dimensional engineering, heteroatom doping, microstructural tailoring. Each dimension material—0D, 1D, 2D, 3D—offers unique advantages: 0D materials ensure uniform dispersion, 1D have short Na + diffusion paths, 2D possess large specific surface areas, 3D provide e − /Na conductive networks. Heteroatom doping elements such N, S, P can tune electronic distribution, expand interlayer spacing carbon, induce Fermi level shifts, thereby enhancing storage capability. In addition, defect engineering improves electrochemical by modifying graphitic crystal structure. Furthermore, suitable structure design, particularly closed structures, increase capacity, minimizes side reactions, suppress degradation. future studies, optimizing exploring co‐doping, developing environmentally friendly, low‐cost anode methods will drive application high‐performance long cycle life

Sodium-ion batteries have been the focus of interest in recent years due to abundance and cost-effectiveness sodium resources globally as opposed lithium. In this work, sulfur-doped graphene oxide (SGO) was synthesized using a straightforward, one-step, cost-effective, eco-friendly chronoamperometric method at room temperature. The resulting powder then utilized active anode material for Na-ion batteries. surface SGO powder, which consists approximately three layers with 19 sp 2 hybridized carbon rings domain size about 50 nm, is covalently doped –C-SOx-C- (x = 2,3) groups. deduced diffusion coefficient from electrochemical impedance spectroscopy galvanostatic intermittent titration technique measurements NIBs range 10 −11 –10 −12 cm .s −1 . At 0.1 C rate, initial discharge capacity recorded 256.7 mAh.g rate. addition, retention long-term cycling 100 cycles rate 99.85%. unique structure allows us achieve satisfactory performance capability, potential further enhancement.
