The hybrid flow battery (HFB) uses one or more electroactive components deposited as a solid layer. The major disadvantage is that this reduces decoupled energy and power. The cell contains one battery electrode and one fuel cell electrode. This type is limited in energy by the electrode surface area. HFBs include zinc–bromine, zinc–cerium, soluble lead–acid, and all-iron flow batteries. Weng et al
Among the three flow batteries, vanadium redox is the most mature technology of flow battery. Both the sections and tanks contain vanadium in sulfuric acid, but at different charge states.

Flow batteries are ideal for large-scale energy storage solutions, such as: In summary, flow batteries offer a flexible and efficient solution for large-scale energy storage by decoupling
Essentially, a flow battery is an electrochemical cell. Specifically, a galvanic cell (voltaic cell) as it exploits energy differences by the two chemical components dissolved in
Weng et al. reported a vanadium– metal hydride hybrid flow battery with an experimental OCV of 1.93 V and operating voltage of 1.70 V, relatively high values.
In contrast, vanadium flow batteries, which are non-flammable and thermally stable by design, offer a safer and more predictable option for stationary energy storage applications.
The commercialized flow battery system Zn/Br falls under the liquid/gas-metal electrode pair category whereas All-Vanadium Redox Flow Battery (VRFB) contains liquid-liquid electrodes.
