Energy materials


Solid state ionics: bulk, interfaces and integration in devices

This symposium will focus on recent developments in the field of solid-state functional materials with distinctive electronic and ionic transport properties and their interfaces to develop the next generation energy and smart devices.


The development of solid-state materials with tailored electronic and ion transport properties is paramount for the optimization of state-of-the-art devices for energy conversion and storage (batteries, photovoltaics, fuel cells, gas sensor and electrolyzers) and smart devices like memristors providing routes for the development of next generation systems with improved performances.

The optimization of the performance of these devices is controlled by the mass and charge transport properties occurring at the bulk, interface and surface level of solid-state materials. It is therefore paramount to gain quantitative understanding of these processes to provide routes for rational design of ionic and/or mixed ionic-electronic conducting materials and optimized interface engineering. This symposium will focus on fundamental and applied aspects of solid state ionic materials covering new practices for theory and simulation of transport properties and materials discovery, recent experimental developments in synthesis and processing and novel advanced characterization techniques of functional materials and interfaces including in situ and operando methodologies.  In addition, for the implementation of innovative concepts into enhanced devices, new methodologies for engineering ionic and electronic transport in functional oxides will be discussed.  The symposium will also serve as a platform to discuss sustainable and low-cost synthesis and fabrication routes including the development of novel devices and the optimization of processing and fabrication tools. Some of the main applications and devices to be discussed will be electrolysis, photocatalysis, batteries, fuel cells, membranes, supercapacitors, memristors, thermoelectric and hybrid devices.
