A promising technology for performing that task is the flow battery, an electrochemical device that can store hundreds of megawatt-hours of energy — enough to keep thousands of homes running for many hours on a single charge. Flow batteries have the potential for long lifetimes and low costs in part due to their unusual design.
Inside an Invinity Vanadium Flow Battery (VFB) Invinity''s products employ proprietary technology with a proven track record of global deployments delivering safe, reliable, economical energy storage. Here''s how our vanadium flow batteries work. The fundamentals of VFB technology are not new, having been first developed in the late 1980s.
A vanadium flow battery uses electrolytes made of a water solution of sulfuric acid in which vanadium ions are dissolved. It exploits the ability of vanadium to exist in four different oxidation states: a tank stores the negative electrolyte (anolyte or negolyte) containing V(II) (bivalent V 2+) and V(III) (trivalent V 3+), while the other tank
