In this work, thermal, chemical and plasma treatments have been employed to modify the surface of the graphite felt to improve the electrochemical activity of the redox flow cell. The influence of the variables of each of these processes on the generation of surface functional groups and on changes in the obtained surface area have been examined.
It is expected that the liquid phase environment is conducive to the mobility of the activator, which makes activation mild, controllable, and uniform. Graphite felt is modified by controlling amounts of KClO 3 and NH 4 Cl to obtain the optimum electrochemical catalysis for vanadium redox reactions.
These electrolytes come from the charge–discharge process. Compared with the vast majority of directly modified carbon-based electrodes for VRFBs, the reported porous N/O co-doped graphite felt electrode occupies a dominant position in terms of cycling performance and strategic advances (Table S4).
The modified graphite felt owns multiple-dimensioned defects, including micropore, O-containing group, and N doping, as well as derived structure defect, resulting in improvement of surface area, active sites, and wettability, as well as electronic structure performance.
Our standardized photovoltaic container and energy storage products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
