“…Recently, there have been increased demands on the development of aqueous organic redox flow batteries (AORFBs) because of their large capacity and long cycle life, while still being ecofriendly with the potential to meet the cost target ($100/kWh) for large-scale energy storage system (ESS) that was reported by the United States Department of Energy (DoE). [1][2][3][4][5] In AORFB, energy is chemically stored by redox reactions occurring at two liquid electrolytes containing the dissolved active materials, while power is produced by charging and discharging processes occurring in electrochemical cell consisting of electrodes, a membrane, and bipolar plates. [6][7][8] Cell performances, such as the delivered capacity, efficiency, and durability, can be improved by the enhanced design of cell components and the increase in electrolyte concentration.…”

4,5-dihydroxybenzene-1,3-disulfonic acid (Tiron) and anthraquinone-2,-7-disulfonic acid (AQDS) are interesting redox couples for aqueous quinonebased redox flow batteries (QRFBs) because of their high solubility and good reaction reversibility in acidic condition. Tiron is rate-determining material due to its slow reaction kinetics. To improve that, Tiron is transformed into 2,4,5,6-tetrahydroxybenzene-1,3-disulfonic acid (TironA), which is effectively formed during the first cycle of QRFB. Once TironA is formed, a desirable two-electron redox reaction with stable and reproducible charge and discharge step of QRFB occurs, although the electron transfer of TironA is still lower than that of AQDS. To further facilitate that of TironA, oxygen (O 2 ) and nitrogen (N 2 ) plasma-treated carbon felt (CF) electrodes are suggested. Oxygen functional groups formed onto CF by O 2 plasma become the active sites for redox reaction of TironA. As the amount of oxygen functional groups formed increases, the redox reactivity of TironA is enhanced. In contrast, when N 2 plasma is used, pyrrolic N and quaternary N are mainly formed. With the formation, (i) hydrogen atoms within pyrrolic N act as proton donor and interact with oxygen groups of TironA and (ii) nitrogen cations within quaternary N interact with the negatively charged atoms of TironA by electrostatic interaction. Thus, both reaction kinetic of TironA and performance of QRFB increase.Regarding the performance of QRFB using N 2 plasma-treated CF, its energy efficiency (EE), discharging capacity, and state of charge are 62%, 17.3 AhrÁL À1 and 64.5% for 50 cycle, which correspond to excellent achievements.

Summary Redox flow batteries (RFBs) using zinc chloride (ZnCl2) and 4,5‐dihydroxy‐1,3‐benzenedisulfonate (Tiron) redox couple is introduced. ZnCl2 and Tiron are used as negative and positive active materials, which are dissolved in near‐neutral pH, ammonium chloride (NH4Cl) supporting electrolyte. Cell voltage of RFB using ZnCl2 and Tiron is extremely high as 1.8 V, while two cellulose spacers are introduced to prevent the growth of zinc dendrite on the membrane. When the performances of RFBs using ZnCl2 and Tiron are measured, their charge efficiency (CE), voltage efficiency (VE), and energy efficiency (EE) are 95, 79, and 75% at 40 mA cm−2, whereas their capacity fading rate is high as 0.12 Ah L−1 per cycle. This is due to the zinc dendrite formed on the electrode of RFB that is attributed to the aggregation of zinc ions. To suppress the aggregation and to preserve active sites for the redox reaction of zinc ions during cycling, the polyethylene glycol (PEG) additive is suggested. Regarding the optimization of PEG, 5000 ppm PEG induces both high efficiencies (97, 81, and 79% of CE, VE, and EE at 40 mA cm−2) and low capacity loss rate (0.03 Ah L−1 per cycle), which are more enhanced performances than those of RFBs operated without PEG. In terms of power density of RFB using ZnCl2 and Tiron, high power density of 144 mW cm−2 is achieved under 120 mA cm−2, which is far better performance than that of other RFBs operated under near‐neutral pH electrolyte.

“…[27][28][29][30][31][32] However, various attempts have been made to replace vanadium active materials due to limitations to cell voltage and the price of vanadium. [33][34][35][36][37][38][39][40] To overcome the limitations, iron-based active materials have been considered, especially irontriethanolamine (TEA) complex (Fe(TEA)), which has already received much attention as an active material for anolyte of alkaline ARFBs. [41][42][43] However, the side reaction of Fe(TEA) occurring during cycling may degrade the capacity of ARFB, followed by its stability.…”

In this study, long-term stability of all-iron aqueous redox flow batteries (all-iron ARFBs) using iron-3-[bis(2-hydroxyethyl)amino]-2-hydroxypropanesulfonic acid complex (Fe[DIPSO]) and ferrocyanide as redox couple is evaluated. In this system, there are two problems to address. First, stability issue of catholyte including ferrocyanide that is worsened under alkali electrolyte and second, unbalanced pH of catholyte and anolyte occurring by the crossover of water molecules during cycling of ARFB, and these degrade the performance of ARFB steadily.
