Vanadium–bromine redox flow battery – VBFB. The vanadium/bromine (V–Br) battery (or 2nd generation VRFB, i.e. G2 V/Br) aims at overcoming the limited energy density on VRFBs (in this context, 1st generation, G1 VFB) while enhancing its advantages. This chemistry has been tested on the small scale, so far.
Power and energy are decoupled or separated inside a vanadium flow battery. Power is expressed by the size of the stack; the energy by the volume of electrolyte in the tanks.
