Synthesis and characterization of TEMPO- and viologen-polymers for water-based redox-flow batteries
Redox-flow batteries that employ redox-active polymers (pRFB) represent a novel energy storage technology requiring innovative materials. Polymers bearing a viologen unit ( N , N ′-dialkyl-4,4′-bipyridines) or a TEMPO radical are synthesized. Acrylamide, poly(ethyleneglycol) methyl acrylates, di(eth...
