Aqueous organic redox-flow batteries (AORFBs) are promising candidates for low-cost grid-level energy storage. However, their wide-scale deployment is limited by crossover of redox-active material through the separator membrane, which causes capacity decay. Traditional membrane permeability measurements do not capture all contributions to in working batteries, including migration and changes ion size charge. Here we present a new method characterizing operating AORFBs using online 1H NMR...
Aqueous organic redox-flow batteries have emerged as promising candidates for the low-cost long-duration energy storage solution that is required to integrate renewable into electricity grid. However, their widescale deployment currently limited by crossover of redox-active material through separator membrane, which leads capacity decay over time. Traditional membrane permeability measurements only account diffusional crossover, and do not capture all contributions transport in working...
There is an urgent need for new energy storage solutions that will support the decarbonization of electricity grid. Aqueous organic redox flow batteries are low-cost, long-duration devices in process being commercialized this application; however, their operational lifetime limited by electrolyte decomposition and crossover. These degradation processes generally studied separately, so relationship between two poorly understood. Previously, it had been assumed main contribution to battery...
