Institut Charles Gerhardt de Montpellier strongly participates to the VIDICAT project with two distinct teams involved.

The first team “Aggregates, Interfaces and Materials for Energy” (AIME) associates competence in innovative synthesis routes to hierarchical materials with tailored architecture and in surface reactivity and the chemistry of interfaces applied to energy storage and conversion.

The perspectives of the research are two-fold: elaboration of original materials enabling emerging energy technologies and the study of the interfacial properties and mechanisms governing exchange of energy and matter at various interfaces.

The team aims in investigating innovative electrode materials for lithium and post-lithium batteries especially through understanding the electrochemical mechanisms to explain the cycling performance and the failure mechanism.

Dr. Laure Monconduit and Pr. Lorenzo Stievano have a strong experience in studying negative electrode materials for lithium- and sodium-ion batteries, while Dr. Romain Berthelot has initiated the research on divalent systems (Mg and Ca) since 2013.

In the frame of the VIDICAT project, the team will evaluate the innovative electrolyte systems made from ionomers with classic electrode materials prepared on site.

The electrochemical activity towards calcium ions will be scrutinized by well-established characterization techniques like X-ray diffraction or InfraRed spectroscopy.

The second team CTMM “Theoretical Chemistry” develops and uses quantum mechanical methods to describe, interpret and predict the physical/chemical reactivity of molecular and solid state systems in different application domains such as photochemistry, homogenous/heterogeneous catalysis and energy conversion and storage.

In the VIDICAT project, CTMM is involved in the electronic structure characterization of ionomers & polymers, and in the investigation of interfaces between active materials and polymer electrolytes.

Dr. Marie-Liesse Doublet has a renowned expertise in the development of computational and conceptual approaches to energy materials for batteries. Pr. Jean-Sébastien Filhol has developed new methodological tools to tackle the challenging problem of interface electrochemistry through full ab initio procedures and Dr. Mouna Ben Yahia is an expert in IR/Raman spectroscopy.

In the frame of the VIDICAT project, these theoretical tools will be applied to a series of ionomers to determine the best combination of polymer and anions for the battery performance.
