Offer DescriptionGeneral contextOver the past few decades, the world has witnessed a revolution in energy storage development: Li-ion batteries. However, this rapid progress also comes with a major challenge in the context of sustainable development, namely compensating for the limited availability of mineral materials and the energy cost of their extraction from the earth's crust. Through this PhD Scholarship, we are seeking to promote the use of a new generation of organic materials in order to offer fewer impacting alternatives for energy storage. The potential of organic chemistry is immense, thanks to low energy costs and rich and versatile synthetic route that allow the creation of tailor-made organic materials. , Despite these advantages, organic materials do encounter some obstacles, such as their solubility in organic electrolytes and their low conductivity, necessitating respectively electrolyte engineering and the excessive use of carbon black.Objective of the PhD projectWithin the framework of this 3-year doctoral contract, the SPIDER project aims to explore the innovative use of tailor-made electroactive macromolecules as electrode materials for solid organic electrode and associated batteries. The objective of the thesis is to focus on new advanced macromolecular materials with controlled solubility and architecture. Project is divided in three interconnected tasks which are: Synthesis and spectroscopic characterization of electroactive macromolecules, Advanced characterization of organic-based materials and evaluation of electrochemical properties in battery configuration of synthesized compounds.Sébastien Gottis et al, Voltage Gain in Lithiated Enolate-Based Organic Cathode Materials by Isomeric Effect, ACS Appl.

As a consequence, very good experience in organic chemistry, multi-step synthesis and characterization of these materials (NMR, TG-DSC-MS, IR and X-ray diffraction) is mandatory. Prior experience in electrochemistry and in the characterization of polymers, supramolecular interactions, polymer electrolyte engineering, electrode formulation and cell assembly would be an advantage. An ability to communicate results clearly and concisely is preferred (French, English B2).Additional InformationWork Location(s)Number of offers available 1 Company/Institute Laboratoire de Réactivité et Chimie des Solides Country France City Amiens GeofieldWhere to apply WebsiteContact WebsiteSTATUS: EXPIRED
