The vanadium flow battery (VFB) as one kind of energy storage technique that has enormous impact on the stabilization and smooth output of renewable energy. Key materials like membranes, electrode, and electrolytes will finally determine the performance of VFBs.
Vanadates are another important vanadium-based electrode materials due to their high output voltage, stable skeleton and fast ion diffusion coefficient. However, most of these materials have low theoretical specific capacity, which limits their practical applications.
This is where vanadium-based compounds (V-compounds) with intriguing properties can fit in to fill the gap of the current battery technologies.
A vanadium redox-flow battery is a promising technology for stationary energy storage. It uses vanadium pentoxide (V 2 O 5) for electrolyte production, which helps reduce system costs and compete with other chemical energy storage systems.
Vanadium-based oxides/sulfides were considered as the ideal next-generation electrode materials due to their high capacity, abundant reserves and low cost. However, the inherent low conductivity and ion diffusion coefficient limit their practical applications in lithium ion batteries.
However, due to the inherent poor conductivity, the cycle life and rate performance of traditional vanadium-based oxide electrodes cannot meet the practical needs. In general, when electrode materials are reduced to nanometer scale, the transport distance between ions and electrons is greatly shortened.
