Sulfonated Polybenzimidazole Membranes: How Sulfonation Affects Properties, Stability, and Performance in Vanadium Redox Flow Batteries

Advanced Energy Materials, Volume 15, Issue 30, August 12, 2025.
Sulfonation of OPBI increases the electrolyte uptake and thus increases the conductivity. Simultaneously, the more open structure increases access to vanadium ions. However, it appears that sulfonation deactivates the sites which are attacked by VO2+. This allows stable and highly efficient vanadium redox flow batteries.
