SOLID ELECTROLYTE

Solid electrolyte will be an important focus area for CIC Energigune because a breakthrough in solid electrolyte will not only improve the safety and manufacturability of Li-based batteries by enabling an all solid-state design, but also help advance Li-air batteries by addressing the problems associated with liquid electrolytes. Major challenges for solid electrolytes are conductivity and temperature range, especially at very low temperatures. The two main research lines of this group are related to ceramic and polymer electrolytes.

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.

More info

Dr. Kilner is a Professor of Materials Science, former head of the Department of Materials and former Dean of the Royal School of Mines (Imperial College London).

He has been involved in research into ionic and mixed conducting ceramics for 30 years and has published over 250 papers in this and related fields of materials science.

Recently he was appointed as European Editor for the Journal Solid State Ionics. He is the holder of a number of patents relating to fuel cells and gas separation devices and the co founder of a successful spinout company CeresPower Ltd.

Prof. Kilner is primarily interested in studying the exchange and diffusion of oxygen in oxide ceramic materials for applications in devices such as fuel cells, oxygen separators and sensors, and has been instrumental in the development of isotopic exchange SIMS techniques to study these phenomena.

Much of his work is now centred upon the development of the Intermediate Temperature Fuel Cell and improved understanding of surface and interfacial phenomena is crucial for further development of this device.
