TL;DR: The vanadium redox flow battery (VRB) has received wide attention due to its attractive features for large scale energy storage as mentioned in this paper, where the key material of a VRB is an ion exchange membrane (IEM) that prevents cross mixing of the positive and negative electrolytes, while still allowing the transport of ions to complete the circuit during the passage of current.

TL;DR: This review will help to optimize the membrane material for different secondary batteries, and favor the understanding of the preparation-structure-performance relationship of porous membranes in different secondary battery systems.

TL;DR: In this paper, vanadium ion/proton (V/H) selectivity with decreasing pore size distribution has been shown to increase vanadium selectivity of VRB membranes, and the results showed that VRBs assembled with prepared NF membranes exhibited comparable performance to commercialized Nafion.

TL;DR: The CoS3 catalyst plays a critical role in improving the sulfur utilization, especially in high-loading sulfur cathodes (3-10 mg cm-2 ), and the Li2 S/Li2 S2 ratio in the discharge products increased to 5.60/1 from 1/1.63, resulting in a sulfur utilization increase.

TL;DR: Porous polybenzimidazole membranes with ultra-high selectivity and stability were designed and fabricated for vanadium flow batteries as mentioned in this paper, and they are the most promising candidate for VF batteries.
