Redox flow batteries (RFBs) are membrane-separated rechargeable cells with redox electrolytes, offering the potential for large-scale energy storage and supporting renewable grids. Yet, creating a cost-effective, high-performance RFB system is challenging. In this work, we investigate an Fe/Mn alkaline based on [(TEA)Fe-O-Fe(TEA)]3-/4- MnO4-/2- couples theoretical cell voltage of ∼1.43 V. This combination has not been systematically studied previously, but it can lead to very low-cost...
The all-iron flow battery is currently being developed for grid scale energy storage. As with all batteries, the membrane in these systems must meet stringent demands ionic conductivity while limiting unwanted reactant (Fe 3+ ) crossover. In addition, chemistry proton transport across highly desirable to maintain pH levels negative and positive electrolytes. Two membranes are considered, Nafion an in-house composite based on Daramic (a commercial microporous separator) poly(vinyl alcohol)....
Many electrochemical processes involve the reduction of a porous solid metal oxide into pure such as Fray-Farthing-Chen (FFC) Cambridge process 1 for titanium and ULCOWIN 2 iron. With optimal electrolysis cell designs, these would produce efficiently without energy losses to parasitic side reactions. Predictive modeling reaction rate (current) distribution underlying can allow increased efficiency higher electrowinning yields. This be beneficial fields nuclear fuel reprocessing sustainable...
