Vanadium redox battery
A vanadium redox battery is a type of rechargeable energy storage system that uses vanadium ions in different oxidation states to store and release electricity. It operates in a liquid form, with electrolyte solutions circulating between two tanks. During charging, electrical energy converts vanadium ions to higher or lower oxidation states, storing energy. When discharging, these ions revert, generating electricity to power devices or the grid. This design allows for quick, efficient, and flexible energy storage, making it suitable for balancing electricity supply, especially with renewable sources like wind or solar.
