“…The total Ohmic resistance (R ) of the porous electrode is then given by a parallel combination of two resistors (L/σ and L/κ ). As expected, the conductivities of both half-cell electrolytes increase with temperature as shown in previous studies [37].

Systematic steady-state measurements were performed in order to investigate the effect of operating temperature on the individual half-cell reactions in all vanadium redox flow cells. Results confirm that the kinetic losses are dominated by the negative half-cell reaction. Steady-state polarization and AC impedance measurements allowed for extraction of kinetic parameters (exchange current densities, activation energy) of the corresponding half-cell reaction.

A thorough understanding of the flow characteristics of vanadium redox-flow batteries is essential for their improvement. With a combined approach of CFD simulations linked with optical measurements, the distribution in a carbon felt electrode of the vanadium electrolyte as well as of an alternative fluid substitute is compared and in all three dimensions analyzed leading to qualitatively consistent results. Yet, the experimentally observed partially inhomogeneous flow distribution is not predicted by the pseudo-homogeneous porous media CFD model.

“…Xiao et al studied the physical properties of V(II), V(III), V(3.5), V(IV), and V(V) at subzero temperatures. Results showed that the low temperature precipitates could redissolve back into solution after being warmed to room temperature for 30 minutes, proving that the process is reversible.…”

A review of all‐vanadium redox flow battery durability: Degradation mechanisms and mitigation strategies

et al. 2019

Summary The all‐vanadium redox flow battery (VRFB) is emerging as a promising technology for large‐scale energy storage systems due to its scalability and flexibility, high round‐trip efficiency, long durability, and little environmental impact. As the degradation rate of the VRFB components is relatively low, less attention has been paid in terms of VRFB durability in comparison with studies on performance improvement and cost reduction. This paper reviews publications on performance degradation mechanisms and mitigation strategies for VRFBs in an attempt to achieve a systematic understanding of VRFB durability. Durability studies of individual VRFB components, including electrolyte, membrane, electrode, and bipolar plate, are introduced. Various degradation mechanisms at both cell and component levels are examined. Following these, applicable strategies for mitigating degradation of each component are compiled. In addition, this paper summarizes various diagnostic tools to evaluate component degradation, followed by accelerated stress tests and models for aging prediction that can help reduce the duration and cost associated with real lifetime tests. Finally, future research areas on the degradation and accelerated lifetime testing for VRFBs are proposed.
