Organic Redox Species in Aqueous Flow Batteries: Redox Potentials, Chemical Stability and Solubility

Organic molecules are currently investigated as redox species for aqueous low-cost redox flow batteries (RFBs). The envisioned features of using organic redox species are low cost and increased flexibility with respect to tailoring redox potential and solubility from molecular engineering of side groups on the organic redox-active species. In this paper 33, mainly quinone-based, compounds are s...

V5+ degradation of sulfonated Radel membranes for vanadium redox flow batteries.

Insight into the degradation mechanisms of aromatic proton conducting membrane separators for vanadium redox flow batteries (VRFBs) is urgently needed for the development of long lifetime VRFBs. Other than in-cell observations of performance degradation, there is little fundamental evidence on the specific degradation pathways of aromatic ion exchange membranes for VRFBs. Herein we investigated...
