H/F PhD thesis in polymer electolytes for lithium batteries without metal
The Laboratory of Electrochemistry and Physicochemistry of Materials and Interfaces is a UMR (5279) Grenoble –INP, CNRS, UGA and Université de Savoie. The 80 permanent staff and the hundred post-docs, PhD students and internship fellows work around major topics associated with electrochemistry (kinetics, material transport mechanisms), materials (electronic and ionic conductors for electrochemical and photovoltaic generators, photosensitive for photovoltaic cells) and electrochemical engineering. The studies go from the characterization of fundamental mechanisms to the engineering of generators by integrating the durability of materials and systems and the study of their life cycle (second life, recycling). These studies incorporate experimental approaches and modeling.
The Phd student will be part of the MIEL (Materials, Interfaces, Electrochemistry) team of LEPMI located on the campus of Grenoble (Saint Martin d’Hères). The Phd student will have access to all the facilities and equipment of LEPMI and CMTC (Consortium of Common Technical Means). The MIEL (Materials, Interface and Electrochemistry) team has a very broad activity on the design and development of new organic materials for liquid or polymer electrolytes of different electrochemical systems. The polymer theme is to design, control and optimize the chemistry and morphology of functional polymer materials, in order to improve their ionic or electronic transport properties and control their reactivity.
Lithium-ion batteries are considered as the most promising energy storage technology to enable the successful electrification of modern society’s mobility needs. However, beside the necessity for enhanced energy and power, two main issues exist which are the high cost and severe safety concerns. While the first is particularly related to the incorporation of pricey metals as Co, Ni or Cu, the latter is mainly associated to the easily flammable and unstable liquid electrolytes. Within this project, these issues are addressed by realizing all-solid metal-free secondary batteries, employing organic active materials directly deposited on 3D carbon current collectors (CCCs) and single-ion polymer electrolytes (SIPEs). For the successful accomplishment of these challenging tasks, MOLIBE will strongly benefit from the highly complementary strengths and competencies in organic electrode and polymer electrolyte synthesis/characterization, cell fabrication/testing and sustainability evaluation of the French and German partners.
The LEPMI student will be responsible for the synthesis and characterization of high ionic conductivity polymer electrolyte materials with good mechanical properties. Polymeric materials in the form of a membrane shall initially be characterised ex situ to determine their thermal, mechanical, electrochemical, transport properties. The best polymer electrolytes will then be tested in the batteries in collaboration with the other project partners.
Chemistry skills in polymer synthesis and characterization are required. Electrochemistry skills will be appreciated.
