Prof. Byon’s group (in collaboration with Prof. Joo’s group at Pusan National University) reported the design principle of organic molecules utilized for non-aqueous organic redox flow batteries (RFBs). By implementing an extended -conjugation, a cationic functional group, and selective anions, they developed highly soluble, stable, and crossover-resistant heteroarylpyridinium in the form of organic redox-active molecules and showed ~90% capacity retention during 100 cycles in RFBs. ...read more
