vanadium redox power

Vanadium redox-flow batteries are a promising energy storage technology due to their safety, long-term stability, and independent adjustability of power and capacity. However, the vanadium crossover through the membrane causes a self-discharge, which results in a capacity shift towards one half cell. Vanadium Redox Battery (VRB), also called Vanadium Flow Battery (VFB), is alternative to and is gradually replacing lead-acid battery. VRB/VFB is an energy storage solution to ensure uninterrupted power supply no matter in combination with solar pv, wind power, biogas generator or
