Molecular Engineering of Polyoxovanadate-Alkoxide Clusters and Microporous Polymer Membranes to Prevent Crossover in Redox-Flow Batteries

Eric Schreiber et al.

Summary: This study investigates the size-dependent crossover behavior of redox-active vanadium compounds and polyoxovanadate-alkoxide clusters in separators derived from polymers of intrinsic microporosity (PIMs) in nonaqueous electrolyte. The results show that increasing the size of the vanadium species and restricting the pore swelling of PIMs can effectively block active species crossover and improve the efficiency of the battery.

Redox Flow Battery Membranes: Improving Battery Performance by Leveraging Structure-Property Relationships

Craig A. Machado et al.

Summary: Membranes play a critical role in redox flow batteries (RFBs) by keeping redox-active species in the two half cells separate and allowing the passage of charge-balancing ions. While significant advancements have been made in RFB membranes, further developments are needed to consider conductivity, selectivity, stability, sustainability, and cost.

Summary: Redox flow battery (RFB) shows promise in grid-scale energy storage, with early systems based on aqueous electrolytes and newer non-aqueous systems potentially offering higher energy density. The membrane is a crucial component in the second-generation NARFB, which still requires improvements in performance. Composite membranes may be the future direction for advancing NARFB technologies.

Simultaneously Enhancing the Redox Potential and Stability of Multi-Redox Organic Catholytes by Incorporating Cyclopropenium Substituents

Yichao Yan et al.

Summary: High redox potential, two-electron organic catholytes for nonaqueous redox flow batteries were developed by incorporating diaminocyclopropenium (DAC) substituents into phenazine and phenothiazine cores. The DAC groups increase the redox potential and render the second oxidation reversible, stabilizing the oxidized forms of the molecules through resonance delocalization of charge and unpaired spin density.

Multiblock Copolymer Anion-Exchange Membranes Derived from Vinyl Addition Polynorbornenes

Ryan Selhorst et al.

Summary: Block copolymers have shown promise in ion-exchange membranes due to their ability to phase separate into well-defined nanostructures, promoting transport. Conductivity of multiblock copolymers was higher than statistical copolymers, likely due to increased surface-to-volume ratio improving connectedness of ionic domains. Water uptake of copolymers depended on the number and order of blocks.

Comparison of Separators vs Membranes in Nonaqueous Redox Flow Battery Electrolytes Containing Small Molecule Active Materials

Zhiming Liang et al.

Summary: The lack of suitable membranes for nonaqueous electrolytes limits cell capacity and cycle lifetime in organic redox flow cells. The study revealed a trade-off between lifetime and Coulombic efficiency, with nonselective separators achieving more stable performance but suffering from low Coulombic efficiencies, while ion-selective membranes achieving high Coulombic efficiencies but experiencing capacity loss over time. Additionally, when electrolytes are premixed prior to cycling, high Coulombic efficiency can be maintained but capacity is lost due to cell imbalance, which can be recovered by electrolyte rebalancing.
