POLYMER ELECTROLYTES

The main goal of this research line is to develop in the short term a Na-ion or Li-ion based battery with polymer electrolytes as a proof of concept to test its better performance against the existing technologies aiming to solve the safety concerns about them.

The main project will face the development of grafted SiO2 particles/PEO based polymer electrolytes and PEO/modified PSS alloys aiming to evaluate their application in Na or Li/polymer batteries.

This short term goals would be integrated within a long term vision of developing high energy density (both gravimetric and volumetric) batteries, safer than present sodium or lithium ion batteries, with design flexibility and most important minimum hazard level.

Michel Armand, born in France (1946), graduated from Ecole Normale Supérieure (rank 1st); Master in inorganic and organic chemistry (Paris 1968); Ph.D. in Physics (1978); Fullbright Fellow at Stanford University in 1970-1. Directeur de Recherche at Centre National de la Recherche Scientifique (CNRS) since 1989. Invited professor at Lawrence Berkeley Laboratory (1982-83). Professor at University of Montreal (Canada) (1995-2004). Director of the Joint CNRS-UdM International Laboratory on Electroactive Materials  (2000-2004). Resumed as Directeur de Recherche at CNRS in Amiens (France)

Michel Armand has covered during his career several theoretical concepts and practical application in the field of energy-related electrochemistry: electrode materials, inorganic or organic and he ushered the concept of intercalation compounds (1972) and of the sulfur/sulfide redox couple; introduction of the polymer electrolytes for battery application (1978), followed by the introduction of new families highly conductive salts (perfluoroimides like TFSI and FSI) for liquid and polymer electrolytes. Present activities include the study and optimisation of production of carbon-coated Lithium-Iron Phosphate (LiFePO4); new solvating polymers, and techniques to obtain cross-linked networks; Hückel stabilised negative charges. More recently, the use of such anions has resulted in significant advances in the field of ionic liquids. Recent developments include the transition metal fluorosulfates LiFeSO4F as improvements over phosphate positive electrodes.

Michel Armand has authored or co-authored 230 publications; 225 presentations at conferences, of which 185 were invited, 157 patents delivered or pending.  He has been or is the Ph.D. advisor for 23 students.

He is acting or has acted as Editorial Board for several journals (Solid-State Ionics, Journal of Applied Electrochemistry, Synthetic Metals, J. Power Sources, JNMES) and Conferences advisory committee and organisation for 35 international conferences.
