Highly Porous

Highly porous carbon–carbon composite electrodes for the implementation in redox flow battery systems have been synthesized by a novel soft-templating approach. A PAN-based carbon felt was embedded into a solution containing a phenolic resin, a nitrogen source (pyrrole-2-carboxaldehyde) and a sulfur source (2-thiophenecarboxaldehyde), as well as a triblock copolymer (Pluronic® F-127) acting as the structure-directing agent. By this strategy, highly porous carbon phase co-doped with nitrogen and sulfur was obtained inside the macroporous carbon felt. For the investigation of electrode structure and porosity X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and nitrogen sorption (BET) were used. The electrochemical performance of the carbon felts was evaluated by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The N- and S-doped carbon electrodes show promising activity for the positive side reaction and could be seen as a significant advance in the design of carbon felt electrodes for use in redox flow batteries.

Due to the pressing need for harnessing renewable energy, sizable energy storage technologies have become increasingly critical, among which vanadium redox flow batteries (VRFBs) are considered as one of the promising technologies. However, the lack of high-performance electrodes hinders the development of VRFBs. Herein, we report a new ammonia plasma-treated WO3@carbon felt as a high-performance electrode for VRFBs. The ammonia plasma introduces not only N-contained functional groups but also oxygen deficiencies on WO3, which provide additional active sites and improve the conductivity, leading to high catalysis for both cathodic and anodic vanadium redoxes. As a result, the energy efficiency and the power density of the VRFB increase from 78.9% to 86% and from 365.5 mWcm[Formula: see text] to 389.6 mWcm[Formula: see text], respectively. Moreover, the energy efficiency of composite electrodes remains stable for more than 300 cycles. This study provides a new strategy for designing cost-effective, environmentally friendly, and high-performance electrodes for future VRFBs.
