“…This can be further studied in RFBs by using accelerated electrode degradation methods [216]. The effect of fibre diameter on the reaction kinetics of porous electrodes has been modelled [188] [229]), non-metallic catalysts (mesocellular carbon foam [230], Bi [231]) and activated by thermal treatment [232] and acids [233]. The Fe-Cr RFB used carbon felts treated with gold and lead [211].…”

Despite many studies and several extensive reviews of redox flow batteries (RFBs) over the last three decades, information on engineering aspects is scarce, which hinders progress with scale-up and implementation of this energy storage technology. This review summarises cell design requirements then critically considers design, construction and cell features together with their benefits and problems, leading to good practice through improved cell performance, knowledge and experience. Techniques for the characterisation of the reaction environment are illustrated by measurements of mass transport to (and from) electrode surfaces as a function of flow conditions, as well as pressure drop and electrolyte flow dispersion. The effect of design features on performance is illustrated by the effect of process conditions on the components of cell potential. Adequate attention to engineering aspects is seen to be critical to the effective performance of RFBs, particularly during scale-up and long-term operation. Techniques for the characterisation of reaction environment are summarised and a list of essential design and construction factors is provided. Finally, critical areas needing research and development are highlighted.

“…Surface graphitization at 1100 • C and higher reduces this negative effect. Mesoporous/mesocellular carbon foam without and with platinum modification attached to graphite felt has been suggested as positive electrode for a VRFB [229]. The electrochemical performance of electrode and cell was ascribed to the particular porosity and the large density of OH-functional groups on the carbon surface.…”

Flow batteries (also: redox batteries or redox flow batteries RFB) are briefly introduced as systems for conversion and storage of electrical energy into chemical energy and back. Their place in the wide range of systems and processes for energy conversion and storage is outlined. Acceleration of electrochemical charge transfer for vanadium-based redox systems desired for improved performance efficiency of these systems is reviewed in detail; relevant data pertaining to other redox systems are added when possibly meriting attention. An attempt is made to separate effects simply caused by enlarged electrochemically active surface area and true (specific) electrocatalytic activity. Because this requires proper definition of the experimental setup and careful examination of experimental results, electrochemical methods employed in the reviewed studies are described first.

“…According to the reports of González et al 25 and Jeong et al., 26 this study uses the peak current density as a measure of the electrode reactivity, in which a relatively high peak current density corresponds to excellent catalytic activity of the reaction. Figure 2a shows that the CV of the pristine GF in 2,7-AQDS solution is in accordance with that reported by Huskinson et al 9 Table S2 shows the electrochemical data from the cyclic voltammograms of the pristine GF.…”

Redox flow batteries have received wide attention because of their unique advantages such as high efficiency, long cycle life, low operating cost, and independent adjustment of energy power. In this study, five types of anthraquinone derivative organic redox couple were selected, and the surfaces of graphite felt were modified. When the number of functional groups is increased or the substitution position is closer to the carbonyl (C=O) groups, a more pronounced hindrance for the C=O reaction on the benzene ring is observed; thus, the electrochemical performance and reversibility decreases. Sodium 9,10-anthraquinone-2-sulfonate solution is the best organic redox couple in terms of both reversibility and electrochemical performance. It was also found that all the surface treatment methods of graphite felt are beneficial for improving their electrochemical performances. All these superior results demonstrate that the graphite felt treated under air exposure at 550 °C for 3 h exhibited the best electrochemical performance, which might be attributed to the increase in the content of C–OH functional groups.
