Called a vanadium redox flow battery (VRFB), it's cheaper, safer and longer-lasting than lithium-ion cells. Here's why they may be a big part of the future — and why you may never see one. In the 1970s, during an era of energy price shocks, NASA began designing a new type of liquid battery.
Among all the energy storage devices that have been successfully applied in practice to date, the flow batteries, benefited from the advantages of decouple power and capacity, high safety and long cycle life, are thought to be of the greatest potentiality for large scale energy storage applications , .
However, as the grid becomes increasingly dominated by renewables, more and more flow batteries will be needed to provide long-duration storage. Demand for vanadium will grow, and that will be a problem. “Vanadium is found around the world but in dilute amounts, and extracting it is difficult,” says Rodby.
As a result, vanadium batteries currently have a higher upfront cost than lithium-ion batteries with the same capacity. Since they're big, heavy and expensive to buy, the use of vanadium batteries may be limited to industrial and grid applications.
And second, if some of the vanadium in one tank flows through the membrane to the other side, there is no permanent cross-contamination of the electrolytes, only a shift in the oxidation states, which is easily remediated by rebalancing the electrolyte volumes and restoring the oxidation state via a minor charge step.
With the escalating utilization of intermittent renewable energy sources, demand for durable and powerful energy storage systems has increased to secure stable electricity supply. Redox flow batteries (RFBs) have received ever-increasing attention as promising energy storage technologies for grid applications.
