Marked importance of surface defects rather than oxygen functionalities of carbon electrodes for the intrinsic vanadium redox kinetics in flow batteries
The significance of this work lies in the promotion of thin carbon paper as well as its treatment (such as the one presented in this work) as electrodes for flow batteries, in particular VRFB reactions.
Thin pyroprotein coating layers containing numerous oxygen and nitrogen heteroatoms were introduced on the surface of CFs (P-CFs), and their catalytic effects on the redox reaction of V2+/V3+ couples for VRFBs were investigated.
