The "Juche" Flow Battery: A National Pride Inspired by vanadium flow batteries, scientists claim a proprietary design using locally mined zinc. Early tests show 65% efficiency—not stellar, but a start. State media calls it “a revolutionary leap in energy storage self-reliance.”
[pdf] A critical factor in designing flow batteries is the selected chemistry. The two electrolytes can contain different chemicals, but today the most widely used setup has vanadium in different oxidation states.
[pdf] The Dalian Flow Battery Energy Storage Peak-shaving Power Station, which is based on vanadium flow battery energy storage technology developed by DICP, will serve as the city's "power bank" and play the role of "peak cutting and valley filling" across the power system, thus helping Dalian make use of renewable energy, such as wind and solar energy.
