• losses [33]. These losses result accordingly from the necessity to overcome the activation barriers of electrode reactions, the non-zero internal resistance of the cell, and resistance of diffusion and convection of the substrates and products of the electrode reactions. All losses coincide at each point

• photoelectron spectroscopy (XPS). The activity for the vanadium ion redox reactions was evaluated by cyclic voltammetry (CV) to demonstrate the enhancement of both the positive and negative electrode reactions. A full cell test of the vanadium redox flow battery (VRFB) showed a significant decrease of the

• carbonaceous thin film was formed by sublimation, deposition, and pyrolysis of CoPc on the carbon fiber surface during a single heat-treatment step using a conventional crucible. The treatment substantially enriched edge planes and produced an enhanced activity for the positive and negative electrode reactions
