The specific role of water for ion electrosorption at charged interfaces
The aim of the present proposal is the continuation of proposal 1-04-228 in order fundamentally improve the understanding of the active role of water in the EDL formation at charged carbon/aqueous electrolyte interfaces by gaining experimental in-situ access to 1) global ion concentration changes, 2) local ion rearrangement and 3) solvent and wetting effects. This will be done by employing small-angle neutron scattering (SANS) at D22 in an in-situ EDLC cell set-up and contrast variation using H2O and D2O solvents in combination with RbBr, CsCl and SrBr2 salts. The obtained results from this proposed continuation are considered essential to improve the energy storage performance of EDLCs.
