Vanadium Redox Flow Batteries

    Newer Older

    PNNL has designed and is testing a modular 1kW/1kWh vanadium redox flow battery with an optimized stack design. The battery incorporates PNNL’s new electrolyte chemistry, delivering 80% increased power capacity, 90% increased efficiency with about half the operating cost of current vanadium redox flow batteries. The battery also has greater operational temperature range, broadening the potential application scope and potential to store large amounts of energy from renewable yet variable resources, such as solar and wind.

      When they want the vanadium for mass production of these things they will have to talk with American Vanadium Corp. who own the only US-based battery grade vanadium source. It's in Nevada.
