Austrian researchers have replaced heavy metals and rare earths with conventional vanillin in a redox flow battery. The Graz University of Technology team now wants to bring this technology to market.Researchers at TU Graz University of Technology in Austria have developed a redox flow battery that uses conventional vanillin as the electrolyte. They've already patented the separation and refinement process and have published the test results in Angewandte Chemie. The flavoring substance vanillin is one of the few fine chemicals that is extracted from lignin. The researchers, led by Stefan Spirk ...Den vollständigen Artikel lesen ...
