Abstract
We investigated the mismatched kinetics of electrode reactions in VRFB, RuO2, and Bi nanoparticles as the functional components electrodeposited on graphene porous gelatum-graphite bipolar plate (ERGO-GBP) integrated electrode and serving as anode and cathode, respectively. Benefitting from the unique structure and specific functionality, the novel integrated electrodes exhibit excellent electrochemical properties and functionality. The asymmetric VRFB with an RuO2-ERGO-GBP anode and a Bi-ERGO-GBP cathode shows better performance compared to the symmetric VRFB with ERGO-GBP as both anode and cathode, suggesting a feasible strategy to construct asymmetric VRFB with various functionalized ERGO-GBP integrated electrodes.
