Research Interests

With a background in solid oxide fuel cells, my expertise lies in the defect chemistry of mixed ionic-electronic conductors. My research focuses on understanding the fundamental mechanisms of defects and their impact on electrochemical reactions, mass transport, and other electrochemical properties and processes. Additionally, I explore high-temperature photovoltaics using solid oxides to harness their potential for sustainable energy systems.

In the past three years, I have developed a novel electrochemical device: the oxygen ion battery. This innovative energy storage solution utilizes the variable oxide stoichiometry of mixed conductors, leveraging materials similar to those used in solid oxide fuel cells. Operating at high temperatures and relying on abundant elements such as iron, chromium, manganese, titanium, and calcium, the oxygen ion battery avoids the use of critical raw materials like lithium, cobalt, or nickel. As a promising technology for large-scale electrochemical energy storage, it has the potential to play a crucial role in enabling the energy transition to renewable sources.

Recently, I was awarded an EIC Transition Grant for the project Oxybatt, where, together with partners from IREC, we aim to translate these research results into a commercial product. This project is a significant step toward bringing sustainable, high-temperature energy storage solutions to the market.
