Nanoionics and Iontronics are emerging disciplines dealing with the ionic transport properties at the nanoscale and the effect of a tuneable arrangement of ions on the electronic properties, respectively. These two disciplines try to understand and exploit the subtle interplay between electrons and ions and its application to innovative solid state-based devices to promote a revolution similar to the one driven by nanoelectronics few decades ago. In particular, since the main conversion and energy storage technologies are based on ionic, electronic or mixed-ionic electronic conductors (MIEC), these new disciplines are called to revolutionize the energy field by giving rise to entirely new and disruptive technologies [1,2,3]. 

In this talk, I will present our last advances in thin film oxides with ionic conduction for their application in solid oxide cells, lithium ion batteries and switchable devices for information technologies [4,5]. Moreover, I will pay special attention to the characterization of ionic transport phenomena in the nanoscale and for materials in operando conditions [6,7,8]. 

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreements No 824072 (Harvestore) and No.101017709 (EPISTORE). This investigation has been supported by the Generalitat de Catalunya-AGAUR (2017 SGR 1421).
