not only improved in terms of catalysis towards the V3+/V2+ redox reaction (k0= 1.6 x 10-3 cm s-1), but also inhibited the hydrogen evolution reaction (HER), which is one of the main causes of imbalances that lead to battery failure. This has allowed us to achieve an impressive high-power peak output value up to 700 mW cm-2 (Figure 6.22), as well as work at high current density in galvanostatic conditions (i.e. 150 mA cm-2), exhibiting low ohmic losses (overpotential) and great redox reversibility of the device for a conventional single cell. It allows our system to reach a superior Energy Efficiency (71%). An inexpensive, earth abundant, environmentally friendly and scalable synthesis method to boost VRFBs technology based on nitrided CF@TiO2 is presented, being able to overcome certain constrains, and therefore to achieve high energy and power density working conditions. 1000 800 600 400 200 0 0 1.6 1.2 0.8 0.4 0.0 500 1000 1500 2000 j / mA cm-2 PD E CF CF@TiO2 N500 CF@TiO2 N900 Figure 6.22. - Scheme of the power rate for the different electrodes involved in this section. The picture behind shows the GF@TiO2:N after cycling. Therefore, using free-standing TiN nanowires synthesized by a two-step process, in which TiO2 nanowires are first grown onto the surface of graphite felt via a seed-assisted hydrothermal method and then partially converted to TiN through nitride reaction, synergistically coupled with the functionalization (O- and N-groups) done at the surface of the carbon felts making the electrode even more enhanced towards V2+/V3+ redox reaction. An energy efficiency values above 70% have been obtained at high current densities, of up to 300 mA cm-2. In addition, the electrodes exhibit good stability and high capacity retention during the cycle tests. This excellent performance is 107 E/V Power density / mW cm-2
