An overview on the use of metal vanadium oxides and vanadates in supercapacitors and rechargeable batteries

Abstract

Summary Recent increase in the growth of devices that store energy, keeping in mind the scarcity of fossil fuels, has facilitated in focusing our attention on rechargeable batteries and supercapacitors. In this regard, the metal vanadium oxides and vanadates have emerged as a promising electrode material. These materials enjoy the possession of high theoretical capacitance, coupled with the existence of multiple redox states, which help in decreasing the activation energy for redox reactions. A detailed investigation and analyses regarding the influence of morphology, which gets formed at the time of synthesis of these materials, on the electrochemical characteristics of the electrode has been presented here. In addition, the prospects and challenges associated with the commercialization of metal vanadium oxides and vanadates have also been discussed.

Unveiling Hierarchical Zinc-Vanadium Oxide Composite Microflakes as Anode Material for Lithium-Ion Batteries

“…The initial CV curve displayed various reduction peaks in the cathodic scan and similar oxidation peaks in the anodic scan compared to the following cycles. This exposes that discrete Li-insertion reactions occur during the initial discharge process [53,54]. As presented in Figure 5(a), the initial cycle revealed three irreversible cathodic (reduction) peaks positioned at about 2.3, 1.9, and 1.5 V, respectively and they vanish in the subsequent cycles.…”

Synthesis and Characterization of Ferric Vanadate Nanorods for Efficient Electrochemical Detection of Ascorbic Acid

“…Although the majority of these methods can produce CeVO 4 nanoparticles with precise sizes and shapes, the hydrothermally produced Co 3 V 2 O 8 thin nanoplates were reported to work well as cathode materials for LiBs. 18 As a typical class of metal vanadate, nanostructured FeVO 4 is especially noticeable as an active material in Fenton-like catalysts, electrochromic electrodes, and rechargeable Li-ion batteries. 19 In these reported investigations, the bottom-up, hydrothermal method was employed for preparing nanostructures, mainly due to the advantages of adjustable parameters and low working temperature, admitting inexpensive, linear synthesis, and fine electric attributes with potential for mass production of superior sensors, commonly not achievable through conventional solid-state chemical reactions.…”
