This study reports a new hybrid approach toward achieving high volumetric energy and power densities in an electrochemical flow capacitor for grid energy storage. The electrochemical flow capacitor suffers from high self-discharge and low energy density because charge storage is limited to the available surface area (electric double layer charge storage). Here, we examine two carbon materials as conducting particles in a flow battery electrolyte containing the VO 2+ /VO 2 + redox couple. Highly porous activated carbon spheres (CSs) and multi-walled carbon nanotubes (MWCNTs) are investigated as conducting particle networks that facilitate both faradaic and electric double layer charge storage. Charge storage contributions (electric double layer and faradaic) are distinguished for flow-electrodes composed of MWCNTs and activated CSs. A MWCNT flow-electrode based in a redox-active electrolyte containing the VO 2+ /VO 2 + redox couple demonstrates 18% less self-discharge, 10 X more energy density, and 20 X greater power densities (at 20 mV s −1 ) than one based on a non-redox active electrolyte. Furthermore, a MWCNT redox-active flow electrode demonstrates 80% capacitance retention, and >95% coulombic efficiency over 100 cycles, indicating the feasibility of utilizing conducting networks with redox chemistries for grid energy storage. Grid energy storage is a critical component toward the integration of renewable energy technologies and ensuring reliable distribution of electricity.1,2 Numerous flow-assisted electrochemical systems (FAESs) based on different active materials are being pursued including redox flow batteries (RFB), 3-5 semi-solid flow batteries, 6,7 organic-redox flow batteries, [8][9][10] and the electrochemical flow capacitor (EFC).11,12 A flow-architecture provides for scalable and modular systems, decoupled power and energy densities, and a potentially low-cost means for storing energy at the grid level (Fig. 1a).All FAESs utilize active materials either dissolved in an electrolyte solution or suspended in an electrically conductive flow-electrode for scalable energy storage (Fig. 1). Redox-flow batteries and organicredox flow batteries both utilize soluble redox species as the active materials (Figs. 1c and 1d). In traditional RFBs, soluble metal ions (vanadium, cerium, iron, etc.) are used, while organic RFBs utilize soluble organic compounds (e.g. quinones) as active material. Metal ions have been widely studied in commercial RFBs and are the closest technology to be widely used. FAESSs based on organic compounds are new and promising for grid energy storage applications because they do not rely on precious metals, have tunable properties based on their chemical structure, 13,14 and have the potential to be low-cost, durable, environmentally friendly, and scalable. Both of these systems rely on chemical reactions based on heterogeneous charge transfer for charge storage. Vanadium compounds have been known to have sluggish kinetics when compared to quinone-based molecules, which undergo rapid t...

“…For example, MWCNTs [5], graphene nanosheets and carbon nanofibers [6,7], functionalization of carbon surface as N-and Ocontaining groups [8], metals such as Pt [6], Ir [9] and Bi [10] and metal oxides Mn 3 O 4 [11,12], WO 3 [13,14], TiO 2 [15], CeO 2 [16], PbO 2 [17], and Nb 2 O 5 [18] were deposited onto the CF supports to prepare modified electrodes. However, although all this research demonstrated an improvement in electrochemical kinetics, the enhanced power density is rarely discussed in the literature as a complementary performance evaluation to the charge/discharge experiments.…”

Although Vanadium Redox Flow Battery (VRFB) is well suitable for grid-scale application, their power-related cost must be reduced in order to boost the technology to the market, allowing their widespread commercialization. One effective way to make the VRFB a competitive and viable solution could be through the new strategies for improving the electrocatalytic activity of the electrodes with enhanced electrolyte/electrode interface characteristics. The greatly effective and enhanced-electron transfer could increase the current density with the decrement of the stack size. Herein, we report the synergistic effect demonstrated by N-and WO 3 -decorated carbon-based positive electrode, named HTNW electrode, which demonstrates the feasibility of achieving: i) enhanced electrocatalytic activity, indicating high rate towards VO 2+ /VO 2 + couple (promotion of oxygen and electron transfer processes), ii) decrement of the electron-transfer resistance from 75.62 Ω to 12.4 Ω for the pristine electrode and HTNW electrodes, respectively; iii) 51% of the electrolyte utilization ratio at high rates (i.e. 200 mA cm -2 ) with 70% of energy efficiency ; iv) increment of more than 50% of the power-peak in comparison with HT electrode.
