Electrochemistry under confinement in 3- and 2-Dimensionnal electrodes for capacitive energy storage

This presentation will give an overview of the research work achieved on capacitive 3-Dimmensional (porous carbon) and high-rate 2-D redox (pseudocapacitive) materials, and will show the challenges/limitations associated with the development of these materials. Starting with porous carbons, we will present the state-of-the art of the fundamental of ion adsorption mechanism in porous carbons and its practical applications. Moving from double layer to high rate redox materials, we will show how the control of the electrodes structure can help in preparing high power rate electrodes using 2-Dimensional MXene materials. We will show how the electrolyte ion partial desolvation observed when confined in nanopores (porous carbons) or in interlayer spacing (2D materials) can result in a continuous transition from EDL formation to typical intercalation-type battery process, offering new opportunities to design high energy and high power electrodes for electrochemical energy storage devices.
