“…Furthermore,elemental analysis and X-ray photoelectron spectroscopy (XPS) measurements were conducted to detect the oxygen species (Supporting Information, Tables S2 and S3) as they are also believed to be beneficial for Na storage performance. [11] Thevariation in oxygen content (determined by elemental analysis) as function of temperature is plotted in Figure 3c.T he oxygen content decreased from 1.5 wt.% for pristine pitch to about 0.6 wt.% in the temperature range of 100-500 8 8C. As temperature increased, the oxygen content increased to 1.7 wt.% at 600 8 8C, 2.7 wt.% at 700 8 8C, and finally reached the maximum of 2.9 wt.% at 800 8 8C.…”

The comprehensive performance of carbon anodes for Na-ion batteries (NIBs) is largely restricted by their inferior rate capability and safety issues.H erein, as lope-dominated carbon anode is achieved at alow temperature of 800 8 8C, which delivers ah igh reversible capacity of 263 mA hg À1 at 0.15C with an impressive initial Coulombic efficiency (ICE) of 80 %. When paired with the NaNi 1/3 Fe 1/3 Mn 1/3 O 2 cathode,t he reversible capacity at 6C is still 75 %ofthat at 0.15C,and 73 %ofthe capacity is retained after 1000 cycles at 3C.T he enhanced Na storage performance could be attributed to the unique microstructure with randomly oriented short carbon layers and the relatively higher defect concentration. Given its robustness, such al ow-temperature carbonization strategy could also be applicable to other precursors and provide an ew opportunity to design slope-dominated carbon anodes for high safety,lowcost NIBs with excellent ICE and superior rate capability.

“…It is worth mentioning that oxygen functional groups can also be used to improve anode functionality . There are a large variety of oxygen functional groups and some of them are electro‐active in the anode voltage range (0–2.5 V vs Na/Na + ), which could provide extra sodium storage sites to improve the capacity of a carbon anode.…”

“…There are a large variety of oxygen functional groups and some of them are electro‐active in the anode voltage range (0–2.5 V vs Na/Na + ), which could provide extra sodium storage sites to improve the capacity of a carbon anode. Chen et al conducted Fourier transform infrared (FTIR) spectroscopy in order to detect the working oxygen functional groups during the discharge–charge of an oxygen‐rich carbon anode (ORC) . They found that the extra capacity of the ORC was primarily due to the redox between CO groups and sodium ions.…”

“…In addition to the surface‐confined charge storage, functional groups can also facilitate intercalation‐based charge storage. Due to the large covalent radius of oxygen, sulfur, phosphorus or fluorine atoms, functional groups containing them that are between the carbon layers will significantly increase the interlayer spacing . The preparation of graphite oxide suggested that surface oxides would increase the interlayer spacing.…”

The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/smll.201902603. Sodium-ion batteries (SIBs) are promising for large-scale energy storage systems and carbon materials are the most likely candidates for their electrodes. The existence of defects in carbon materials is crucial for increasing the sodium storage ability. However, both the reversible capacity and efficiency need to be further improved. Functionalization is a direct and feasible approach to address this issue. Based on the structural changes in carbon materials produced by surface functionalization, three basic categories are defined: heteroatom doping, grafting of functional groups, and the shielding of defects. Heteroatom doping can improve the electrochemical reactivity, and the grafting of functional groups can promote both the diffusion-controlled bulk process and surface-confined capacitive process. The shielding of defects can further increase the efficiency and cyclic stability without sacrificing reversible capacity. In this Review, recent progresses in the ways to produce surface functionalization are presented and the related impact on the physical and chemical properties of carbon materials is discussed. Moreover, the critical issues, challenges, and possibilities for future research are summarized. Sodium-Ion Batteries

The electronic environment and physicochemical property of carbon materials can be easily tailored and modulated by heteroatom doping. Herein, we demonstrate that net‐like N, O, S triple‐doped microporous carbon nanowires (NOS‐MCNs) as an anode can be designed to improve the electrochemical performance of sodium ion batteries. Ammonium persulfate as oxidant can also provide a nitrogen and sulfur source for S‐containing PPy. The N, O and S atoms are introduced into the carbon skeleton with activation and carbonization processes to modify the surface properties. As an anode, the material exhibits a high specific capacity and a long lifespan (≈301 mA h g−1 at 0.2 A g−1 after 1000 cycles) as well as an excellent rate capability (158 mA h g−1 at an extremely high current density of 10 A g−1). This work offers a facile strategy to synthesize triple‐doped porous carbon materials for sodium ion batteries and other energy‐storage fields.
