The project entitled “Smart Pillared Carbon Materials for Supercapacitors: from fundamental understanding of ion transport to device testing (SPICS)” aims at developing innovative 2D carbon layered materials with enhanced storage capability thanks to the use of storage active pillars. The idea is to go beyond the use of simple mechanical pillars and to introduce polar or redox functionalities to enhance specific interactions with the electrolyte leading to improved charge storage capability. To achieve this goal, a part of the project will be devoted to an in-depth analysis of the charge compensation mechanism through the use advanced electrogravimetric techniques based on the electrochemical quartz crystal microbalance (EQCM). QCM derived techniques (conventional EQCM, QCM coupled with EIS (AC-EQCM) and electroacoustic impedance, EQCM with dissipation monitoring (EQCM-D)) will be employed to understand the impact of these active pillars on the dynamics of ion transfer at the electrode/electrolyte interface, on kinetic rate transfer constants and on faradic reactions occurring, but also to evaluate how the electromechanical stress experienced by the material during cycling affects the electrode structure. The outcome of the project is expected to contribute to the establishment of a virtuous circle enabling the design of improved material to their integration into devices.


Task I: Elaboration of 2D carbon based electrodes (with different types of pillars) on the QCM resonators / Classical structural and morphological characterization of these layers.
Task II: In situ Techniques for Advanced Analysis (transfer/transport properties of species at interface/through the electrode, electromechanical and structural analysis during cycling): EQCM, EQCM-D, AC-EQCM and electroacoustic impedance.
Task III: Analysis/Modelling of the electrogravimetric results (EQCM, AC-EQCM, electroacoustic impedance, EQCM-D) and correlation of these results with the results given by the other techniques.
Task IV: Data presentation, reporting, participation to publication preparation.


- Ph.D. in material science or analytical chemistry with strong skills in electrochemistry, hands-on experience on electrogravimetric methods (EQCM, EQCM-D, AC-EQCM…) and EIS.
- Experience on carbon based energy storage materials synthesis/characterization is appreciated.
- Ability to work as an independent researcher with a high level of scientific judgement and initiative.
- Excellent communication and organization skills.
- Oral and written English proficiency.

Work Context

This post-doctoral project is framework part of an ANR work programme entitled “Smart Pillared Carbon Materials for Supercapacitors: from fundamental understanding of ion transport to device testing (SPICS)” involves the collaboration of three other laboratories (INAC - Institute Nanaoscience et Cyrogenie (Grenoble, France), CIRIMAT - Cirimat Centre Interuniversitaire De Recherche et d'Ingéniérie des Matériaux (Toulouse, France) and LISE - Laboratoire Interfaces et Systèmes Electrochimiques (Paris, France). The prospective post-doctoral researcher will work in two locations in Paris: collaboration between the LISE laboratory and the CSE for the electogravimetric studies. The CSE (UMR 8260, College de France, Paris) and the LISE (UMR 8235, Pierre et Marie Campus, Sorbonne University) are in very close proximity. The position will require reasonable amount of travel between the partners out of Paris (project meetings and collaborative experimental work).
The LISE laboratory is a mix research unit associating the CNRS (National Center of Scientific Research) and Sorbonne University (Jussieu campus, Paris, France), employing 50 persons. The research areas of the "Interfaces and Electrochemical Systems" laboratory are corrosion and its inhibition, surface treatments, energy storage and conversion, as well as the investigation of the behaviour of interfaces in natural environments.
Within the Collège de France (Paris, France), the “Solid state chemistry-Energy (CSE)” is an internationally known laboratory focusing on the fundamental science of materials for energy storage and conversion devices. The main activities of CSE include the structural design of new insertion materials, new Li reactivity mechanisms, the mastering of interfaces, and the exploration of other chemistries beyond Li-ion (such as Na-ion, solid state batteries…).
