“…In Section S3, additional in-plane and through-plane visualizations of the cloth electrode are shown (Figure S3 and S4). Another remarkable structural difference between the paper and cloth electrodes, is the pore morphology, which for the carbon cloth is observed to be more ellipsoidal, similar to other studies that have reported this pattern for hierarchical porous materials [62]. As reported in Table 1, the different microstructural characteristics lead to different intraelectrode properties.…”

At the core of redox flow reactors, the design of the flow field geometry –which distributes the liquid electrolyte through the porous electrodes– and the porous electrode microstructure –which provides surfaces for electrochemical reactions– determines the performance of the system. To date, these two components have been engineered in isolation and their interdependence, although critical, is largely overlooked. Here, we systematically investigate the interaction between state-of-the-art electrode microstructures (a paper and a cloth) and prevailing flow field geometries (flow through, serpentine and four variations of interdigitated). We employ a suite of microscopic, fluid dynamics, and electrochemical diagnostics to elucidate structure-property-performance relationships. We find that interdigitated flow fields in combination with paper electrodes –which features a uniform microstructure with unimodal pore size distribution– and flow-through configurations combined with cloth electrodes –which have a hierarchical microstructure with bimodal pore size distribution– provide the most favorable trade-off between hydraulic and electrochemical performance. Our analysis evidences the importance of carrying out the co-design of flow fields and electrode microstructures in tandem. We hope these results can help researchers and technology practitioners in the design of electrochemical cell for convection-enhanced electrochemical technologies.

“…Electrospinning is a simple method that uses a high voltage to create an electric field on a polymer solution or melt. The physical entanglement of the polymer chains and the evaporation of the solvent or the freezing of the melt allows the formation of fibers in the nanometer scale, with a broad field of applications, including energy harvesting (Laudenslager et al, 2010;Szewczyk et al, 2020) and storage (Mao et al, 2013;Li et al, 2016;Sun et al, 2021).…”

Full Lignin-Derived Electrospun Carbon Materials as Electrodes for Supercapacitors

In the search for more sustainable energy storage devices, biomass-derived materials have been widely researched as carbon source for electrode applications. Here we present the processing of high molecular lignin, an abundant carbon rich biopolymer and byproduct of the pulp and paper industry, into freestanding nonwoven carbon fiber (CNFs) electrodes by using electrospinning. It is worth mentioning that no petrol-derived polymers that are usually included in the electrospinning of lignin, were employed in this work, making these electrodes more sustainable than common lignin-derived carbon electrodes. The effect of the carbonization temperature and oxygen plasma treatment in the electrochemical performance of the CNFs as electrodes for supercapacitors was studied. The upscaling of the processing of lignin into carbon electrodes was also explored by comparing a standard electrospinning set up with a needleless electrospinning equipment that enabled faster and higher throughput. The electrochemical performance of the CNFs increased after plasma treatment of the surface and the electrodes prepared using the standard set up exhibited the highest activity, achieving specific capacitances of up to 103.6 F g−1.

“…However, when the fiber diameter is larger than 2 μm, the improvement in PEMFC performance becomes less significant. Meanwhile, it should be noted that the electrospinning process becomes unstable when fabricating fibers with a larger fiber diameter [52]. In practical application, a fiber diameter of ~2 μm can be adopted for ease of fabrication.…”
