“…Furthermore, hybrid materials related to VO 2 (B) were also developed to apply to the material of the electrodes. For instance, VO 2 (B)/C were synthesized through the hydrothermal method, which exhibited the specific capacitance of 182 F•g −1 when the voltage window limit is −0.6~0.8 V. The VO 2 (B)/rGO composites exhibited a capacity of 456 mAh g −1 [26]. According to the published data, the electrochemical properties of VO 2 (B) as SCs remains to be optimized further.…”

B-type vanadium dioxide (defined as VO2(B)) nanobelts were synthesized through using commercial ammonium metavanadate, oxalic acid via one-step hydrothermal technique. The structure of VO2(B) was characterized using different instruments. N2 adsorption-desorption isotherms revealed that the VO2(B) nanobelts were porous structures where BET surface area was 10.4 m2·g−1, the pore volume was 0.0687 cm3/g, and the average pore size was 42.7 nm. Furthermore, the VO2(B) nanobelts as supercapacitors electrode exhibited a large voltage window (−0.8~1.0 V). The measured capacitance was based on the pseudocapacitance. When the discharge current density is 0.5, 1, and 10 A·g−1, the VO2(B) shows the specific capacitance of 287, 246, and 222 F·g−1, respectively.

“…Authors also examined the formation of byproducts associated with Zn(CF 3 SO 3 ) 2 and Zn(NO 3 ) 2 which suggested that byproducts with large ionic paths can be an essential choice for further improvement in electrochemical processes in ZIBs. Other morphologies such as tetragonal VO 2 hollow nanospheres [108] and composites such as rGO/VO 2 nanobelts composite, [109] PEDOT/VO 2 , [110] etc. have also been explored to demonstrate the performance of ZIBs using VO 2 as cathode material.…”

Vanadium dioxide (VO2) received tremendous interest lately due to its unique structural, electronic, and optoelectronic properties. VO2 has been extensively used in electrochromic displays and memristors and its VO2 (B) polymorph is extensively utilized as electrode material in energy storage applications. More studies are focused on VO2 (B) nanostructures which displayed different energy storage behavior than the bulk VO2. The present review provides a systematic overview of the progress in VO2 nanostructures syntheses and its application in energy storage devices. Herein, a general introduction, discussion about crystal structure, and syntheses of a variety of nanostructures such as nanowires, nanorods, nanobelts, nanotubes, carambola shaped, etc. are summarized. The energy storage application of VO2 nanostructure and its composites are also described in detail and categorically, e.g. Li‐ion battery, Na‐ion battery, and supercapacitors. The current status and challenges associated with VO2 nanostructures are reported. Finally, light has been shed for the overall performance improvement of VO2 nanostructure as potential electrode material for future application.

Vanadium oxides are promising cathode materials for rechargeable aqueous zinc-ion batteries (RAZIBs). However, the selfagglomeration and poor ion/electron conductivity of vanadium oxides in the charge/discharge process usually lead to low capacity and capacity attenuation, which limits their commercial application. Herein, we report a facile and mass-production method for fabricating 3D porous carbon/water-pillared V 2 O 5 nanosheet composites with sandwich structure (PC/V 2 O 5 • nH 2 O), which can further reduce the preparation cost of vanadiumoxide-based cathodes. Moreover, the excellent structural characteristics of PC/V 2 O 5 • nH 2 O not only effectively inhibits the aggregation and stacking of V 2 O 5 • nH 2 O but also increases the contact area between the active substance and the electrolyte, which is conducive to the transport of zinc ions and improves the electrochemical performance of RAZIBs. The PC/V 2 O 5 • nH 2 O cathode displays an excellent rate performance (325.3 mAh g À 1 at high current density 20 A g À 1 ), a high specific discharge capacity of 415.4 mAh g À 1 at 0.5 A g À 1 , an outstanding cyclic stability, and capacity retention (after 1000 cycles the capacity retention rate about 97.1 %). Ex situ XRD patterns reveal that the charge/discharge process of the PC/V 2 O 5 • nH 2 O electrode undergoes a reversible intercalation and conversion process. The method used in this work provides an idea for large-scale synthesis of vanadium-based cathode materials for multivalent batteries.
