“…The microstructure of SNQL-3 could be described as nanoscale pores surrounded by a combination of rumpled and twisted graphene sheet fragments which partially were longrange disordered structure. The compositions of SNQL-3 were investigated using SEM equipped with energy dispersive spec- [14,29,[40][41][42] troscopy (EDS), as shown in Figure 3g-j S5 and S7 (Supporting Information), respectively. Only SL displayed a prominent lamellar structure, indicating that carbonaceous materials could be efficiently recombined into carbon sheets by KCl.…”

“…It should be emphasized that the achieved performance exceeds that of many recently reported hard carbons (Figure 4c). [14,29,[40][41][42] The detailed compari-son was listed in Table S5 (Supporting Information). The promising electrochemical performance can be ascribed to the hard carbon structure with a large surface area, abundant open pores, and dopant atom, which allow for the adsorption of capacitance and improve the electrochemical storage property.…”

The slow solid diffusion dynamics of sodium ions and the side‐reaction of sodium metal plating at low potential in the hard carbon anode of sodium ion batteries (SIBs) pose significant challenges to the safety manipulation of high‐rate batteries. Herein, a simple yet powerful fabricating method is reported on for “egg puff”‐like hard carbon with few N doping using rosin as a precursor via liquid salt template‐assisted and potassium hydroxide dual activation. The as‐synthesized hard carbon delivers promising electrochemical properties in the ether‐based electrolyte especially at high rates, based on the absorption mechanism of fast charge transfer. The optimized hard carbon exhibits a high specific capacity of 367 mAh g−1 at 0.05 A g−1 and 92.9% initial coulombic efficiency (ICE), 183 mAh g−1 at 10 A g−1, and ultra‐long cycle stability of reversible discharge capacity of 151 mAh g−1 after 12,000 cycles at 5 A g−1 with the average coulombic efficiency of ≈99% and the decay of 0.0026% per cycle. These studies will undoubtedly provide an effective and practical strategy for advanced hard carbon anode of SIBs based on adsorption mechanism.

“…[ 36 ] The integrated area ratio of D‐band to G‐band (I D /I G ) is usually used to evaluate the degree of graphitization of carbon materials. [ 37 ] It is unexpected that the CF‐M‐ x samples have lower I D /I G values compared with the original CF; in the meantime, with increasing bead:CF ratio, the I D /I G value is continuously decreased, and finally a lowest I D /I G of 1.08 is achieved for CF‐M‐200. This implies that the CF‐M‐200 has fewer structural defects, i.e., normally higher graphitization degree, which seems to be contrary to the XRD results.…”

Oxygen doping is an effective strategy for constructing high‐performance carbon anodes in Na ion batteries; however, current oxygen‐doped carbons always exhibit low doping levels and high‐defect surfaces, resulting in limited capacity improvement and low initial Coulombic efficiency (ICE). Herein, a stainless steel‐assisted high‐energy ball milling is exploited to achieve high‐level oxygen doping (19.33%) in the carbon framework. The doped oxygen atoms exist dominantly in the form of carbon‐oxygen double bonds, supplying sufficient Na storage sites through an addition reaction. More importantly, it is unexpected that the random carbon layers on the surface are reconstructed into a quasi‐ordered arrangement by robust mechanical force, which is low‐defect and favorable for suppressing the formation of thick solid electrolyte interfaces. As such, the obtained carbon presents a large reversible capacity of 363 mAh g−1 with a high ICE up to 83.1%. In addition, owing to the surface‐dominated capacity contribution, an ultrafast Na storage is achieved that the capacity remains 139 mAh g−1 under a large current density of 100 A g−1. Such good Na storage performance, especially outstanding rate capability, has rarely been achieved before.

With the rapid development of renewable energy and the growth of energy demand, sodium‐ion batteries have attracted much attention from researchers as a promising energy storage technology. Hard carbon anodes are considered to be the most promising anodes of sodium‐ion batteries because of their low sodium storage potential, high capacity, wide range of raw materials, and environmental friendliness. However, the rate capability and initial coulombic efficiency of hard carbon hinder the further commercialization of hard carbon. This review provides a concise overview of the three microstructures and four sodium storage mechanisms of hard carbon and comprehensively introduces the latest research progress on strategies to effectively improve the electrochemical performance of hard carbon anodes, which are categorized into structural and morphology design, precursors selection, electrolyte optimization, surface engineering and pre‐sodiation as modification strategies. In addition, we also encapsulate the current research progress on sodium‐ion full batteries and look forward to the developmental prospects of hard carbon anodes in sodium‐ion batteries.This article is protected by copyright.
