“…4,5 As a promising alternative, aqueous redox ow batteries (RFBs) have received considerable attention because of their intrinsic non-ammability and excellent scalability with decoupled power and energy capacities. [6][7][8][9][10][11] However, allvanadium RFBs (VRFBs), which are in the demonstration stage, still suffer from high electrolyte cost. 10 Batteries based on inorganic redox active species such as LIBs and VRFBs will always be subject to resource limitations and thus incur high costs.…”

“…The most recent trend in literature investigates non-aqueous solvents, ion-selective electrocatalysis, and organic redox couples to increase energy and power density, and lower costs. [27][28][29][30] One key advantage that non-aqueous RFBs have over aqueous RFBs is the potential for enhanced electrochemical operating windows. 31,32 The result of the wider voltage spectrum can enable higher energy dense RFBs and lower-cost grid storage systems.…”

The future of sustainable energy will consist of renewable energy integration with the critical enabler-energy storage technologies such as batteries. Specifically, redox flow batteries represent one type of grid-scale energy storage device with long life spans of at least 10 years and capabilities like peak shaving and load leveling. As more experimentalists are investigating the novel nonaqueous redox flow batteries (NRFBs) to achieve higher energy densities, there is a lack of mathematical models for NRFBs to understand the rate-limiting factors of the battery system. This paper is one of the first modeling efforts to understand key characteristics of NRFB system and operation with experimental validation. The model presented concludes that the nonaqueous solution (tetrabutylammonium vanadium(v) bis-hydroxyiminodiacetate and tetrabutylammonium vanadium(iv) bis-hydroxyiminodiacetate diluted in acetonitrile) is a promising half–cell solution for future redox flow battery couples. One key advantage for this half–cell is its generally facile reaction kinetics and insignificant activation losses. The real limiting factors for the half–cell are ohmic losses and mass transport losses with high sensitivities. Mass transport losses can be controlled by increasing concentrations of active species and staying within a SOC region of 10-90%.
