Thursday 26th October 2017 @ 11:00 am - 12:00 pm
Seminar title: FROM LITHIUM-ION TO SODIUM-ION BATTERIES: A MATERIALS PERSPECTIVE
Venue: Nanoforce Seminar Room, Joseph Priestley Building, Queen Mary University of London, Mile End campus, London
Speaker: Prof. Philipp Adelhelm of the Institute of Technical Chemistry and Environmental Chemistry at Friedrich-Schiller-University Jena in Germany
Sodium-ion batteries with non-aqueous electrolytes have been already studied in the late 1970s and early 1980s, along with lithium-ion batteries. The efforts, however, were not successful and research on NIBs was largely abandoned. With the discussion on sustainable materials and the demand for large scale electrochemical energy stores, research on sodium-ion batteries has recently seen a revival with the hope to find low-cost battery systems, especially for stationary storage. . In a bit simplified way, a sodium-ion battery could work just as a lithium-ion battery as shown in the figure below. What happens when replacing Li+ by Na+ in a battery? Or, in other words: What is the impact of ion size on the cell chemistry of rechargeable battery systems?
This presentation will give an introduction into sodium-ion batteries, their recent development and materials requirements. Progress during the last years will be summarised and selected examples on comparing electrode materials for “Li-ion” with “Na-ion” chemistries will be given. The high energy battery systems “Metal/air” and Metal/Sulfur” will be discussed as well as the peculiar behaviour of graphite and CuO as electrode materials.
