The Bejger lab has recently published an article title "Desymmetrized hexasubstituted radialene anions as aqueous organic catholytes for redox flow batteries" in the Journal of Chemical Communications. The article may be found here.
Here is an abstract of the published work:
"Negatively substituted trimethylenecyclopropane dianions, a subclass of hexasubstituted radialenes, are candidates for use as active species in redox flow batteries (RFBs) due to their stability in water, reversible electrochemistry, and tailorable synthesis. Hexacyanoradialene disodium is investigated as a pH 7 aqueous organic catholyte. The dianion and radical anion are stable in air and aqueous solutions at neutral pH. Systematic introduction of asymmetry via step-wise synthesis leads to enhanced solubility and higher capacity retention during galvanostatic cycling. An aqueous flow cell comprising a diester-tetracyanoradialene catholyte, sulfonated-methyl viologen as the anolyte, and a cation exchange membrane provides an operating Vcell = 0.9 V, 99.609% coulombic efficiency, and minimum capacity fade over 50 cycles."
Congratulations to the Bejger lab and all the authors on this publication!
