■タイトル
Neutron Total Scattering and computational modelling as a method to probe electrolyte structure confined in nanoporous carbon supercapacitor electrodes
■要旨
Nanoporous carbon supercapacitor electrodes are gathering significant interest due to the anomalous increase in performance as pore sizes approach the size of the ions in the electrolyte. Supercapacitors are an important emerging class of energy storage devices essential for high-power applications in society's transition to emission-free energy sources. However, direct observation of the double layer is difficult for many reasons: The system involves a large number of components, the carbon and the electrolyte are both disordered systems, and the device must be under electrical bias.
The NIMROD neutron total scattering instrument at ISIS has the unique capability of being able to access a wide range of length scales present in condensed matter, while also utilising isotopic contrast to highlight the position of hydrogen-containing cations in the pores of nanoporous carbons. The data from NIMROD is corrected for hydrogen inelasticity and placed on an absolute scale; the structure can be refined computationally using the empirical structural refinement method to gain a detailed insight into the confined liquid structure of both the electrolyte ions and solvent molecules.
In this work, we have observed the presence of tetraethyl ammonium ions in the nanopores of the industry standard carbon electrode materials YP-50f, YP-80f and the mesoporous ordered carbon CMK-3, as a proof of concept for in-situ electrochemical measurements of similar systems.
