Fully integrated into the 2020-2030 trajectory of the (FET-Flagship) European initiative (H2020 & Horizon Europe) Battery 2030+ (website: https://battery2030.eu/: Manifesto & Roadmap), this postdoctoral fellow research contract aims at exploring and developing the potential of electrolytes 2.0 combining self-assembly/healing faculties with an efficient transport of Li+ cations: Thermotropic Ionic Liquid Crystals (TILCs). These tailored-made cationic conductors represent the fusion of two classes of functional materials: stimuli-responsive thermotropic liquid crystals and organic (cat)ionic (Li+) conductors. The postdoctoral fellow will implement and (proof of concept) characterize self-healing lithium metal batteries (LMBs) using dynamic 1D, 2D and 3D supramolecular organizations of TILCs to ensure efficient cation transport between their Li metal anode and their cathode .
Electrochemist by training, specialized and experienced in the electrochemical storage of energy, His/Her first mission will be to decipher the multi-scale correlations linking the structures and ionic transport properties within TILCs (in bulk) & TILCs/electrodes interphases in post-lithium-ion energy storage devices (batteries/pouch cells) via the ex situ vs. in situ vs operando monitoring of bulk vs. interfacial (electro)chemical processes and their impact on key performance indicator (KPIs) values of self-healing LMBs developed within the framework of the H2020 project "HIDDEN". He/She will also have the (secondary) mission of characterizing the structure & dynamics of TILCs synthesized by the CNRS + UGA & Specific Polymers partners.
Using HIDDEN's self-healing LMBs as experimental platforms for proof-of-concept demonstrations, He/She will address two fundamental questions for self-assembling/healing mesomorphic organic electrolytes during the course of his/her postdoctoral research project: i) the role of (1D vs. 2D vs. 3D) dimensionality on percolation and nanoconfinement of charge carriers in hierarchically self-organized electrolytes and ii) the dynamic mosaicity and management of defects in stimuli-responsive mesomorphic (macro)molecular ionically conducting materials, with or without external stimuli.
To realize his/her missions under the H2020 project HIDDEN at the UMR5819-SyMMES lab, He/she will benefit from state of the art Lab. (HyBRID-EN : https://www.symmes.fr/en/Pages/STEP/Hybriden.aspx) and European (e.g. ESRF & Soleil) large-scale facilities dedicated (ex situ/in situ/operando) characterizing multi-modal/physics platforms, making use of and/or combining:
-NMR spectroscopies(High Resolution-NMR, Solid-State NMR, Pulse-Field Gradient NMR (PFG-NMR), and NMR relaxometry)
-Differential Scanning Calorimetry (DSC)
-Polarized Optical Microscopy (POM)
-(Synchrotron-based) X-ray (SAXS/WAXS) Scattering and X-ray ((nano-)Computed Tomography & Coherent (nano-beam) Diffractive) Imaging
-Potentiostatic Electrochemical Impedance Spectroscopy (PEIS)
-Galvanostatic Cycling with Potential Limitation (GCPL)
-Galvanostatic Intermittent Titration Technique (GITT)
The PDF applicant should hold a PhD degree in Electrochemistry (or Materials Science) in the field of Electrotrochemical Energy Storage, with strong skills, track record experience and practical and hands on expertise in i) the design/assembly of electrochemical cells (batteries & pouch cells) and ii) the advanced characterizations (CV, PEIS, GCPL, GIIT) of high-performance rechargeable batteries (e.g. Lithium-Ion/metal batteries (LiBs/LMBs)).
Know-how in the design/characterization of functional soft matter (e.g. smart organic ionic conductors) and /or experience in the multi-scale characterizations of the structure/dynamics/ion transport properties correlations of ionic conductors and rechargeable batteries (LiBs/LMBs) will be considered as a plus.
Proven capacities for scientific autonomy and a force of proposal to carry out innovation breakthrough-oriented multidisciplinary projects combined with a tropism for synergistic work in a multidisciplinary team involved in collaborative projects at the interfaces of chemistry, electrochemistry, physicochemistry and physics of functional (macro)molecular materials and electrochemical energy storage devices will be considered most valuable
Excellent communication and writing skills (especially in English) will be are equally important criteria with respect to academic qualifications and scientific merit for the selection of the postdoctoral fellow.
