In this article, we review the vanadium-based technology for redox flow batteries (RFBs) and highlight its strengths and weaknesses, outlining the research that aims to make it a commercial success.
Despite these advantages, the deployment of the vanadium battery has been limited due to vanadium and cell material costs, as well as supply issues.
An important feature of vanadium redox flow batteries is the independent sizing of their power and energy rating. Energy capacity, which depends on a reactant concentration and electrolyte volume, and power, which depends on the area of electrode and the number of cells in a stack, can be independently optimized to suit specific user requirements.

However, there are still many problems that need to be solved.
There are four kinds of vanadium oxides in monovalence vanadium oxides, which are VO, V2O3, VO2, and V2O5, respectively. Due to the instability of VO at room temperature, the applications of VO in energy storage and electrocatalysis were not found. So in this section, the V2O3, VO2, and V2O5would be. As one of the most common vanadium oxides, the V2O5 was applied in alkali metal-ion batteries [18,19,20], zinc-ion batteries (ZIB) [21,22,23],. Zhang et al. grew a V2O5 nanosheet array on carbon fiber and applied it to the anode material of sodium-ion batteries. The specific capacity was 241. In terms of the application of V2O5 in lithium-ion batteries cathode materials, the common strategy is to synthesize the special morphology to improve the Li+ storage performance by interface effects.
