Mechanism-Based Design of a High-Potential Catholyte Enables a 3.2 V All-Organic Nonaqueous Redox Flow Battery

An extremely high-potential catholyte leading the first 3.2 V all-organic flow battery.

Scientific Achievement

Development of an extremely high-potential catholyte leads to the first 3.2 V all-organic flow battery.

Significance and Impact

This work illustrates an attractive integrative strategy for new battery electrolyte development and sets the state-of-the-art voltage window for such systems.

Research Details

  • Mechanistic analysis, computation prediction and chemical synthesis are combined to achieve an unprecedentedly high-potential catholyte.
  • This material was paired with a phthalimide derivative to achieve a proof-of-principle 3.2 V all-organic RFB.
