CERAMIC ELECTROLYTE

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.

Tasks:

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.

Anna Llord├ęs Gil completed her Ph.D. in Chemistry in 2010, at the Institute of Materials Science of Barcelona (ICMAB-CSIC) with the thesis titled "Superconducting Nanocomposite Films Grown by Chemical Methods: Synthesis, Microstructure and Properties", co-directed by Prof. Xavier Obradors and Dra. Susagna Ricart. During her PhD she did two research stays; at the University of Hasselt (Belgium), in the Inorganic and Physical Chemistry Group with Prof. Marlies Van Bael, and at CRISMAT (Caen, France), in the Crystallography Group with Prof. Daniel Chateigner.

After her Ph.D., she did a 3-year Postdoc (2010-2013), at the Lawrence Berkeley National Laboratory (US), where she joined the group of Dr. Delia Milliron, at The Molecular Foundry. There, she focused on the development of new electrochromic nanocomposite films for energy-saving window applications. In 2013, her work received the R&D 100 Award, as one of the most innovative technologies and resulted in the creation of a start-up company (Heliotrope Tech.) and several patents. After her Post-Doc, she was promoted to Project Scientist.

Since December 2014 she is an Ikerbasque Research Fellow at CIC EnergiGUNE, where she joined the Solid Electrolyte group. Her main research interests include the study of new composite materials with tailored ion transport properties. By controlling structure and composition, at multiple length scales, she aims to tackle fundamental limitations in current solid electrolyte materials.
