Sulfonated para‐Polybenzimidazole Membranes for Use in Vanadium Redox Flow Batteries

Dense sulfonated para-PBI membranes (MS-PBI) are tested in the VRFB. The conductivity is 10 times lower than reported for MS-PBI gel membranes, but 10 times higher than that of meta-PBI. The influence of membrane preparation process, thickness, and operating temperature on the VRFB performance is investigated. Energy efficiency reaches 92% at 80 mA...
