Abstract

Performance metrics have significantly improved as a result of recent technological developments. Round-trip efficiencies have risen to over 80% thanks to advanced membranes with improved ion selectivity and decreased crossover as well as optimized electrode materials with hierarchical porosity and catalytic surface modifications. Mixed-acid electrolytes have a 30–40% higher energy density due to their improved solubility limits and wider operating voltage windows. There is hope for more advancements with emerging techniques like metal-air hybrid systems organic flow chemistries and innovative nanofiltration membranes. These technical features make RFBs the perfect choice for renewable integration applications that need long duration for energy time- shifting and quick response for grid stabilization with little performance degradation over decades of use. RFBs show remarkable promise for the circular economy. At end-of-life the liquid electrolytes can be fully recovered and reprocessed establishing a closed-loop material cycle. Following basic filtration and chemical balancing the vanadium electrolyte for VRFBs maintains its value and can be utilized again in new systems. Because the mechanical parts are recyclable according to standard procedures the overall recyclability is higher than 90%. These features minimize lifetime environmental effects and resource depletion linked to grid-scale energy storage deployment while also being in line with sustainability goals.
