Goals: The aim of this work is to develop ceramic materials as solid electrolytes for advanced Li and Na batteries with optimized composition and microstructure using cost-effective processing.


The development of ceramic processing of the chosen materials into dense (>95%) thin (or thin film structures) suitable for battery applications.
The development of selected compositions by experimental optimization guided by computer simulation techniques.
Perform compatibility and durability studies between electrodes and electrolyte.
Build and test prototype cells from the optimized system.

Research highlights:

Thin film electrolytes fabricated by Pulsed Laser Deposition (PLD)
Novel perovskite and garnet materials synthesized with high conductivity.
Novel processing routes determined for ceramic electrolytes.
Li NMR used to elucidate details of processing.

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.

Dr Frederic Aguesse received his PhD degree from Imperial College London, UK, in 2012 following a Master Science degree at the University of Louis Pasteur in Strasbourg, France. Since his early start he worked with worldwide institutes such as ETH Zürich, MIT Boston, the London Centre of Nanotechnology and the National Institute for Materials Science, Japan, where he worked as research visitor in 2010. In February 2012, Frédéric Aguesse started as a postdoctoral researcher at CIC EnergiGUNE on ceramic materials for all-solid state batteries and post-mortem analysis of commercial batteries.

Dr. Aguesse focused his thesis work for the development of functional ceramics and thin films by means of physical vapour deposition techniques. He studied the electric, magnetic and multiferroic properties of crystalline materials. At CIC EnergiGUNE he works in developing all-solid state batteries and dedicates his skills for the development of thin films and preparation of ceramic materials with highly conductive Li-ions properties. Frédéric constantly looks for developing new skills and aptitudes and he is acquiring further experience by developing an inspiring protocol for post-mortem analysis and characterisation of aged batteries in close collaboration with international battery companies.
