V and oxidative limits by 0.32 V. The GdmTFSI electrolytes do not show evidence of passivation on the GC electrode, with further cycling showcasing no significant decrease in catalytic current and a lack of a passivation peak, contrarily to 21 m LiTFSI (Fig. ). The lower saturation limit of GdmTFSI(aq) may be unable to prevent the dissolution of any decomposition products that result in the formation of a passivating layer. Meanwhile, measurements in acetonitrile (ACN) reveal the salt's stability (Fig. ). ). The positive value for TFSI -, despite being believed to be chaotropic, is explained by the size and hydrophobicity of the ion. Taking these values results in a Jones-Dole B-coefficient of -0.13 for the Gdm + , indicating the Gdm + acts as a chaotrope relative to Li + , producing an overall less kosmotropic salt compared to LiTFSI. When While we believe chaotropicity is the main function of GdmTFSI, studying Li + dynamics in the bulk and at interfaces in the GdmTFSI + LiTFSI mixtures could provide insights into any entropic effects and will be studied going forward.
