“…Additionally, the use of additives, such as amines, urea, phosphoric acid, or for example, iron containing additives can lead to the introduction of heteroatoms to boost the performance of the biomass-derived carbon electrodes [33]. These strategies lead to an increase of charge accumulation at the interface electrode/electrolyte, which in turns promotes the adsorption of positive and negative charges to the surface of the electrode [34,35].…”

“…Soaked mature seeds of scaphium scaphigerum were carbonized in the presence of urea to introduce nitrogen in the resulting AC. After hydrothermal treatment, the freeze-dried product was mixed with an excess of urea (4:1 by mass) and carbonized in argon at 850 • C to obtain N-doped AC, with a surface area of 299.42 m 2 g −1 [34]. XPS measurements reported a nitrogen content of 8.2%, while carbonizing at 700 • C or 1000 • C led to a lower nitrogen content, and a urea free carbonization at 700 • C resulted in 1.3% nitrogen.…”

The development of alternative energy storage technologies is key to advance renewable energy resources. Among them, redox flow batteries (RFBs) have been identified to be one of the most promising technologies in the field of stationary batteries. The carbon-based electrodes in these batteries are a crucial component and play an important part in achieving high efficiency and performance. A further leap into this direction is the design of fossil-free materials by incorporating sustainable alternative resources as the carbon component in the processing of the electrodes. The use of biomass as carbon precursor for electrode applications has also been a focus of research for other energy storage devices and in the case of RFBs, it has become an emergent topic in recent years. This short review presents the recent advances in the design of biomass-derived carbon materials as electrodes in RFBs, strategies to enhance their electrocatalytic properties, challenges, and future outlook in the design of sustainable electrode materials.

“…Based on that, when plasma pressure and plasma duration time are within the optimal condition ranges, the electrochemical performances of active species are best. 17,37,38 Pyrrolic N is a heterocyclic aromatic organic compound that has a five-membered ring with N─H bond (Figure S3). 39 Hydrogen atoms contained in pyrrolic N can act as proton donor for facilitating the redox reaction of TironA and interact with the oxygen groups within carbonyl group of TironA.…”

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.

VO 2 + /VO 2+ and V 3+ /V 2+ solutions are designed as the positive and negative active species for VRFB, respectively ( Jiang et al, 2021b ; Lv et al, 2021 ). A H + exchange membrane is placed in the middle to form a closed loop.…”

In this work, nanosized P-doped SnO2 (SnO2-P) was prepared by a sol–gel method as a catalyst for the V3+/V2+ redox reaction in vanadium redox flow battery. Compared with SnO2, the electrochemical performance of SnO2-P is significantly improved. This is because P doping provides more active sites and shows greatly improved electrical conductivity, thereby increasing the electron transfer rate. As a result, SnO2-P shows better catalytic performance than SnO2. The SnO2-P modified cell is designed, and it exhibits an increase of 47.2 mA h in discharge capacity and 8.7% in energy efficiency compared with the pristine cell at 150 mA cm−2. These increases indicate that the modified cell has a higher electrolyte utilization rate. This study shows that SnO2-P is a new and efficient catalyst for vanadium redox flow battery.
