Performance of nanostructured zinc vanadates for energy storage applications: Current status and future perspectives

The domain of energy storage has shown a great deal of interest in zinc vanadates (Zn-V-O systems) because of its promising electrochemical qualities, which include high energy density, good thermal stability, and the capacity to function over a wide temperature range. These substances, which are researched for their potential application in batteries and supercapacitors, combine the positive qualities of vanadium and zinc oxides to provide a compound that can be used for a variety of energy storage needs. Zinc vanadates are composed of zinc (Zn), vanadium (V), and oxygen (O), forming compounds that can exist in several stoichiometries and structures. The specific properties of zinc vanadates, including their bandgap, electrical conductivity, and ion intercalation behaviour, can vary significantly depending on their crystal structure and synthesis method. Their peculiar electrochemical features, such as their various oxidation states that facilitate multi-electron transfer processes and result in high specific capacities and energy densities, are what give them prominence. This article explores the use of zinc vanadates in energy storage applications, emphasizing their advantages, recent developments, and mechanisms.
