Charge/discharge and cycling performance of flexible carbon paper electrodes in a regenerative hydrogen/vanadium fuel cell

Modelling of redox flow battery electrode processes at a range of length scales: a review

“…115 Recently, the modication of carbon paper electrodes by reduced graphene oxide for improved battery performance has been studied by means of XCT and correlated with other methods. 271,272 It was demonstrated for the rst time that XCT can resolve between carbon paper and carbon-based deposited layers. Fig.…”

“…Another topic to be addressed is the roles of micropores and adsorption on RFB performance (depending on the chemistry). Many experimental studies have shown "activation" of the carbon electrode enhances performance, 272,343,344 and this is normally explained in terms of changes in the functional groups on the electrode surface. However, this activation may also generate micropores and increase the surface area, and there are few modelling studies to investigate if the micropores play a role in the enhancement of battery performance or not.…”

Evaluation of a Non-Aqueous Vanadium Redox Flow Battery Using a Deep Eutectic Solvent and Graphene-Modified Carbon Electrodes via Electrophoretic Deposition

“…Deposits were performed for one side of the carbon paper sample only, as double-sided deposits resulted in poorer performances [43]. N-G deposits faced the membrane in order to minimize ohmic losses as demonstrated from results we obtained from our previous studies on regenerative fuel cells [32] and VRFBs [31]. The mass loading of N-G on the CP was 0.25 mg cm −2 , giving a good indication of decent deposits.…”

“…An in-house designed and assembled reactor having a 5 cm 2 active area was employed for RFB testing. The zero-gap flow-by RFB cell [5,31,32] is illustrated in Figure 2a along with a photo of the operational cell (Figure 2b). Graphite plates with a double serpentine flow-channel (CNC (Computer numerical control, and commonly) machined in-house) were employed for distributing the electrolyte across the active area and to electrically connect to the Cu current collector as for a previous study on aqueous-based VRFBs [31].…”
