University of Helsinki
Our next colloquium in the spring series is by Tanja Kallio from Aalto University on May 17th in Exactum B123.
Tanja Kallio, D.Sc. (Tech.), is an associate professor in electrochemistry and physical chemistry at the Aalto University School of Chemical Engineering. Her Electrochemical Energy Conversion Group investigates materials and components for such electrochemical conversion and storage applications as low temperature fuel cells and electrolysers, and lithium and sodium batteries. The core theme is improving sustainability by utilizing materials and energy more efficiently during the conversion processes. The work is carried out in close collaboration with various universities, research organizations and industry and funded majorly by Business Finland, European Union, Jane and Aatos Erkko Foundation and Research Council of Finland. Tanja Kallio is a member of the Hydrogen Europe Research and EC Batteries Europe working groups furthering the research and innovation actions in these fields.

Abstract of the talk:
Lithium-ion batteries are in our everyday use in various applications extending from portable devices to vehicles and energy storage. The forecasted exponentially growing need of lithium batteries puts pressure on developing more efficient and sustainable lithium batteries by increasing their lifespan and energy content. I will introduce you one approach for understanding high energy cathode materials operation and ageing – that is fabricating and investigating artificial cathode electrolyte interfaces (ACEI). This approach enables gaining insight into how protective interfaces formed in conventional batteries during the battery operation affect the battery functioning and ageing. Technological relevance of this approach relays on the capability of ACEIs for enhancing battery lifespan without sacrificing the performance.
