Context
The position is part of the “RAISE 2024” (towaRd All solId State battery in 2024), a five years project funded by the E2S (Energy Environment Solutions) Initiative
(https://e2s-uppa.eu/en/index.html).
The RAISE2024 project aims at developing polymer based solid-state batteries up to a Technology Readiness Level 6 in close partnership with three academic laboratories, IPREM (Institute of Analytical Sciences and Physical Chemistry for the Environment and Materials – ), IPRA-DMEX (Multidisciplinary Institute for Applied Research) and PDP (research center Pau Public Law) as well as two major international companies, Arkema and SAFT. The main objective of the project is to develop an advanced battery system based on solid electrolytes, which represents a new field in the rechargeable battery domain. Electric vehicles and renewable energy storage are the applications targeted, with safety, high energy density, no self-discharge, a long stability/cycle life, easily scalable, low cost as main requirements.
Goals
The postdoc candidate will be in charge of the study and characterization of the buried interfaces in solid-state batteries based on Lithium ion-conductive polymers. Within the framework of a close collaboration between Arkema France (Lacq), IPREM (Pau) and TOTAL-SAFT (Bordeaux), the work will be devoted to the study and the characterization of solid electrolytes and battery stacks through the implementation of a specific Focused Ion Beam (FIB) cross cut methodology coupled to the analysis of the materials by several surface techniques including Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS), Auger Electron Spectroscopy (AES) and X-ray electron spectroscopy (XPS). The candidate will also highly participate to the evaluation of the material properties in terms of ionic conductivity, electrochemical stability, dendrite mitigation and mechanical properties.
Position ans assignments
The Postdoc position also include teaching duty at UPPA (64 h per year).
