The intercalation capacity at low potential of carbon‐based anode plays a significant role for developing potassium ion batteries (PIBs) with high energy density. However, the inferior rate and cyclic performance caused by repeated insertion/extraction of large K+ tremendously restricts the practical application of PIBs. Herein, a quasi‐graphite structure with abundant edge‐nitrogen doping, micropores structure, and enhanced graphite nanodomains via in situ polymerization of oligoaniline in‐between graphene oxide blocks and subsequent carbonization is proposed. The macro‐ordered multilayered structure with micro‐ordered graphite nanodomains can provide efficient K+ insertion/extraction channels, thus greatly increasing the intercalation capacity at low potentials. Moreover, the high edge‐nitrogen doping (97%) is of great importance for improving K+ transfer kinetics, particularly at high current densities. As a result, the anode exhibits a high discharge capacity below 0.5 V (303 mAh g−1 at 0.05 A g−1), outstanding rate performance (113 mAh g−1 at 5 A g−1), and long‐term cycle stability (176 mAh g−1 at 1 A g−1 after 2000 cycles). The K+ intercalation mechanism and enhanced kinetics are systematically probed by in situ Raman spectroscopy, ex situ X‐ray diffraction (XRD) spectra, and theoretical calculations. This results demonstrate that the construction of quasi‐graphite with heteroatom doping is feasible for large ion storage.

“…In Figure S8 (Supporting Information), the maximum stress of the SCS under 25 °C after 0.4 s was 0.577 MPa, much higher than that of both HCS (0.0244 MPa) and TH-HCS (0.0073 MPa), indicating that the inner hollow structure could release stresses from the inside out during sodiation, promoting the stability of the carbon sphere over long-term cycling. [17] More importantly, compared with hollow structure, through-hole struc-ture could further relieve internal stress. The maximum stress of TH-HCS was lower than that of HCS, and it only concentrated at the around of through-hole.…”

“…In addition to the aforementioned through-hole and hollow structures that improve the wettability of electrolyte and relieve the internal stress, the defective structure also has a significant effect on the migration kinetics of Na + . [17] To reveal this effect, the corresponding density functional theory (DFT) calculation was performed. The Na + migration energies in two carbon samples with various defect structures were calculated (Figure 3d,e).…”

Boosting the ultralow temperature (below −30 °C) performance of Na‐ion hybrid capacitors (SIHCs), which integrate the high energy density of batteries with the high output power and long life of supercapacitors, is critical for the application of advanced electronics in extreme environments. However, their low‐temperature performance, especially fast charging capability, is hindered by difficult desolvation and slow pass solid electrolyte interphase (SEI) together with sluggish diffusion within the electrode. Herein, a “single‐solute–single‐solvent” electrolyte is developed and a through‐hole hollow carbon sphere (TH‐HCS) is constructed, and it is demonstrated through theoretical calculations and experimental investigations that the weakly solvated structure and high ionic conductivity facilitate the Na+ transportation at low temperatures, the highly fluorinated SEI facilitates the Na+ migration, and the through‐hole hollow structure alleviates the volume expansion during sodiation, thus ensuring fast kinetics and structural stability. As expected, TH‐HCS using this electrolyte exhibits a high specific capacity of 87.5 mAh g−1 after 11 000 cycles at 1.0 A g−1 and −40 °C. Coupled with activated carbon, the assembled SIHC displays an energy density of 106.1 and 52.0 Wh kg−1 at 25 and −40 °C, respectively, far exceeding the performance of commercial energy storage systems at low temperature.
