“…The variation of the conductivity shows two regions refereed as I (T<550) and II (T>550), associated with two activation energies separated by one temperatures T=550K. Thus it is likely that the observed change may be due to the change in the conduction mechanism, because there is no melting or phase transition as seen in the thermal analysis study reported earlier [24]. The same behavior is also found by H. Nefzi et al [15] for layered hybrid compound.…”

Pre‐intercalating ions between VO layers is considered to be an effective strategy to modulate the interlayer spacing of 2D vanadium oxides. However, the rigid pre‐intercalated ions hardly keep stable during repeated charging/discharging process and their sizes limit the extent of interlayer spacing expansion, which inevitably lead to poor rate capability and cycle stability. In this work, aliphatic diamines are adopted as pre‐intercalated guests to elastically modulate the interlayer spacing of VO layers by tuning the chain length of the organic diamine molecules. Benefiting from the strong interaction between the terminal doubly protonated amine and the polar negative oxygen bridge of the VO layers, the aliphatic diamine molecules can act as a structural stabilizer between the layers and boost fast Na ion diffusion (10−8 to 10−10 cm2 s−1). The sodium ion battery based on the first synthesized 1,6‐hexanediamine pre‐intercalated vanadium oxide supported on nickel foam hybrid cathode achieves a large specific capacity of 597 mAh g−1 at 0.09 A g−1, as well as superior rate performance and cycling stability. This work provides a strategy to elastically modulate 2D layered materials with tunable interlayer spacing for batteries based on large‐size‐ions.

“…It was then left to dry for 24 h at 80 8C. The black color of the powder suggests that some V 5+ ions have been reduced to V 4+ by the decomposition of the organic compound [33].…”

“…Vanadium oxides have also been of particular interest because of the variety of possible structures that are formed, leading to the possibility of tailoring the structure for cathode use. We have been successful in the hydrothermal synthesis of vanadium oxides for the past decade, revealing the effect of pH on the vanadium coordination and proposing a general mechanism of hydrothermal reactions [33][34][35][36].…”
