Flux XII is an organic energy solutions start-up company developing flow battery technology based on work from Dawei Feng, the Y. Austin Chang Assistant Professor of Materials Science and Engineering in UW–Madison's College of Engineering. The Flux XII team has developed proprietary flow battery chemistries with improved safety, lifetime, area footprint, energy efficiency, and cost. What are these materials made of? Carbon (C12). These organics are crafted from earth's most abundant elements and can be sustainably produced domestically. They are then dissolved in benign, pH neutral water to power Flux XII's flow battery system. No more mining or hectic supply chains when you grow your battery material at home! Not only are these carbon-crafted energy solutions safe, sustainable, and low-cost, but they show enhanced energy density, chemical stability, and energy efficiency over any existing flow battery technology.
