There are five different types of VRFBs: conventional, hybrid, membrane-less, stacked, and nanostructured VRFBs. . The vanadium redox battery (VRB), also known as the vanadium flow battery (VFB) or vanadium redox flow battery (VRFB), is a type of rechargeable flow battery which employs vanadium ions as charge carriers. During the charging process, an ion exchange happens across a membrane. This process changes the oxidation states of the vanadium ions, leading to efficient electricity. . Quite a number of different materials have been used to develop flow batteries. However many variations have been developed by researchers including membraneless, organic, metal hydride, nano-network, and semi-solid. . The battery uses vanadium ions, derived from vanadium pentoxide (V2O5), in four different oxidation states. These vanadium ions are dissolved in separate tanks and pumped through a central chamber where they exchange electrons, generating electricity.
