Results for tag: "Iron Flow Batteries"

Iron flow batteries are a type of rechargeable battery that uses iron as its primary energy storage component. This technology falls under the broader category of redox flow batteries (RFB), which function on the principle of electrochemical reduction and oxidation of elements to store energy. Distinct from solid-state batteries like lithium-ion, iron flow batteries circulate a liquid solution containing iron salts through an electrochemical cell during charging and discharging cycles. The advantages of iron flow batteries include their scalability, relatively low cost due to the abundance of iron, and environmental safety, as they do not use rare or hazardous materials. Furthermore, they offer long cycle lives and are particularly well-suited for stationary applications, such as grid energy storage where long-duration energy storage is beneficial for managing intermittent renewable energy sources like solar and wind power.
