In the past decade, lot of attention has been put on electrochemical double layer capacitors (EDLCs), also known as supercapacitors, since they are one of the most promising electrochemical energy storage devices for high power delivery or energy harvesting applications.

During this presentation, we will show how the careful design of the material/electrolyte interface can help in designing high energy density carbons for supercapacitor applications. The first part of the talk will be dedicated to the study of the ionic fluxes and ion adsorption into porous carbon materials. The combination of several techniques like in-situ NMR spectroscopy, EQCM and simulations has then been used for studying the ion confinement effect in carbon nanopores and helped in developing our basic understanding of the electrolyte/carbon interactions in confined pores. A last part of the presentation will be presented some perspectives beyond the carbon-based supercapacitors offered by2-Dimensional MXene materials, for increasing the energy density of these devices.
