Aromatic Diester Anolytes for Nonaqueous Redox Flow Batteries

Batteries &Supercaps, EarlyView.
Owing to their extended π‐conjugation 2,2′‐bipyridyl aromatic diesters are stable in singly‐ and doubly‐reduced states. In a redox flow battery a high battery voltage of 2.82 V can be realized and a capacity a capacity retention of 99.5% per cycle for 260 cycles.

Boron‐Formazanate Complexes as Tunable Redox‐Active Materials for Non‐Aqueous Redox Flow Batteries

Chemistry – A European Journal, EarlyView.
Boron‐formazanates were investigated as a chemically tunable and electrochemically robust class of redox‐active materials for nonaqueous flow batteries. Electrochemical characterization, coupled with postmortem analysis, uncovers B─F bond cleavage as a key degradation pathway contributing to capacity fade.
