Figure 5. TRYP-based derivatives and the performance for AORFBs^[47]. (A) Synthesis of TRYP-SO₃H; (B) Schematic illustration of an AORFB. Aqueous organometallic and all-organic battery using TRYP-SO₃H and K₄[Fe(CN)₆]/BQDS in neutral pH, and the corresponding redox mechanisms of TRYP-SO₃H, K₄[Fe(CN)₆], and BQDS. (C, E) CVs at 50 mV s^-1 in 1.0 M KCl of C: 1.0 mM TRYP-SO₃H (green trace) + 1.0 mM K₄[Fe(CN)₆]·(orange trace) and E: 1.0 mM TRYSO₃H (green trace) + 1.0 mM BQDS (purple trace); (D, F) Charge-discharge energy density and charge-discharge capacity plots of neutral pH aqueous organometallic and all-organic materials for AORFBs using 5.0 mM of TRYP-SO₃H in 1.0 M KCl as anolyte and (D) 10.0 mM of K₄[Fe(CN)₆]·or (F) 5.0 mM of BQDS as catholyte.
