Fig. 2: The selectivity and conductivity of thin-film composite membranes.

From: Thin-film composite membrane breaking the trade-off between conductivity and selectivity for a flow battery

Fig. 2

a Vanadium concentrations in the magnesium sulfate solution at the permeate side versus time. b Cross-membrane conductivity of different membranes. c, d The change of cross-membrane conductivity (c) and area resistance (d) with the sulfuric acid concentration. The area resistance of the selective layer equals to the difference between the area resistance of the substrate and of the IP2-0.15. Data behind each average are represented by smaller symbols. Nf represents Nafion. Source data of b–d are provided as a Source Data file.
