In-situ anomalous X-ray diffraction on the working electrode of electric double layer capacitors

We propose to use in-situ anomalous X-ray diffraction to study the working electrode of an electric double layer capacitor. Varying the photon energy at the absorption edge of the electrolyte ions will allow us to obtain ion-specific information and extracting the pair distribution functions, specifically ion-ion, ion-water, and ion-carbon interactions.
