Are vanadium redox flow batteries suitable for stationary energy storage?
Vanadium redox flow batteries (VRFBs) can effectively solve the intermittent renewable energy issues and gradually become the most attractive candidate for large-scale stationary energy storage. However, their low energy density and high cost still bring challenges to the widespread use of VRFBs.
Why are innovative membranes needed for vanadium redox flow batteries?
Innovative membranes are crucial for vanadium redox flow batteries to meet the required criteria: i) cost reduction, ii) long cycle life, iii) high discharge rates, and iv) high current densities. To achieve this, various materials have been tested and reported in literature.
Can polymeric membranes be used in vanadium redox flow batteries (VRB)?
This review focuses on the use of polymeric membranes in Vanadium Redox Flow Batteries (VRB) and discusses various factors to consider when developing new membrane materials, with or without the addition of non-polymeric materials.
How to determine the optimal flow rate of a vanadium electrolyte?
A dynamic model of the VRFB based on the mass transport equation coupled with electrochemical kinetics and a vanadium ionic diffusion is adopted to determine the optimal flow rate of the vanadium electrolyte by solving an on-line dynamic optimization problem, taking into account the battery capacity degradation due to electrolyte imbalance.
Why does a vanadium electrolyte deteriorate a battery membrane?
Exposure of the polymeric membrane to the highly oxidative and acidic environment of the vanadium electrolyte can result in membrane deterioration. This is due to the oxidative attack on the membrane by the vanadium ions. Furthermore, poor membrane selectivity towards vanadium permeability can lead to faster discharge times of the battery.
How does corrosive vanadium electrolyte affect battery performance?
The graphite BPs in the corrosive vanadium electrolyte is easily eroded due to CO 2 gas evolution on the positive side of the VRFB electrode [92, 93]. The severe heterogeneous surface corrosion results in electrolyte leakage across the BP that significantly deteriorates the battery performance, which ultimately leads to battery failure.
