Job Description
Thesis Subject
Thin-film amorphous electrolytes, such as those based on LiPON, are at the heart of microbatteries, which are increasingly used in the health sectors. They also represent promising coatings for electrodes in solid-state batteries. However, one of their major limitations is their moderate ionic conductivity. A promising approach to increase the conductivity of these electrolytes is to incorporate other network formers than P, such as Si, S or B. Nevertheless, a rational improvement in conductivity using this strategy is limited by our lack of knowledge of the atomic-level structure of these amorphous thin-film electrolytes other than LiPON. In particular, a major question is whether all the chemical elements are incorporated into the same phase or a separation between different amorphous phases occurs. The aim of this project is to understand how combining different network formers modifies the atomic-scale structure of these thin-film electrolytes and increases their ionic conductivity. To answer this question, a series of compositions containing mixed network formers will be synthesised using a physical vapour deposition technique known as RF magnetron sputtering. The ultimate goal of this project is to establish the relationships between composition, atomic-scale structure, and ionic transport in the synthesized amorphous electrolytes, in order to guide the rational design of new amorphous solid electrolytes with improved ionic conductivity compared to LiPON.
Your Work Environment
Created in 1995, the Bordeaux Institute of Condensed Matter Chemistry (ICMCB) focuses its research on Solid State Chemistry, Materials Science and Chemistry and Process: designing, preparing, shaping and characterizing materials in order to discover, control and optimize specific functions. The ICMCB carries out fundamental research on model materials and/or materials with potential applications.
The ICMCB is a UMR with an average of 280 agents (permanent and non-permanent), with 3 tutelles, hosted by the CNRS and in total ZRR. The position is located in a sector covered by the Protection of Scientific and Technical Potential (PSTP), and therefore requires, in accordance with the regulations, that the arrival of the agent be authorized by the competent authority of MESR.
