Bis(diisopropylamino)cyclopropenium-arene Cations as High Oxidation Potential and High Stability Catholytes for Nonaqueous Redox Flow Batteries

Development of a new catholyte with both high oxidation potential and high stability for nonaqueous redox flow batteries

Scientific Achievement

Development of a new catholyte with both extremely high potential and much improved cycling stability.

Significance and Impact

This work illustrates a delineated strategy for new catholyte development and shows a convergent strategy to combine two known redox-active centers to generate a new catholyte material.

Research Details

  • Mechanistic analysis, computation prediction and chemical synthesis are combined for the development of a new generation high-potential catholyte.
  • This electrolyte was paired with a viologen derivative to achieve a proof-of-principle 2 V all-organic RFB.
