Description
In situ small angle X-ray scattering (SAXS) is a suitable technique to analyze global ion fluxes and local ion re-arrangement in nanoporous carbon-based supercapacitor electrodes upon charging and discharging.[1,2] Recently, we have extended our studies to include volumetric changes of the electrodes during operation. Therefore, a novel hierarchical carbon material with ordered mesoporosity and tunable disordered microporosity was synthesized. This system provides the unique possibility to track electrode expansion and compression on the nanometer and the macroscopic scale by combining in situ SAXS and electrochemical dilatometry.[3]
