报告摘要：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 Figure 1. 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 summarized 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 behavior of graphite and CuO as electrode materials.

报告人简介： Prof. Philipp Adelhelm is a materials scientist and received his education at the University of Stuttgart and the Max-Planck-Institute for Metals Research. For his PhD studies on carbon materials, he joined Prof. Markus Antionetti at the Max-Planck-Institute for Colloids and Interfaces in Potsdam. For his post doc, he joined the he Debye Institute of Nanomaterials Science in Utrecht, The Netherlands, studying hydrogen storage materials. He then joined the group of Prof. Janek at Giessen University for his habilitation. Since 2015, he is full professor at the University of Jena. His current research interest is on fundamentals of alternative battery concepts with the major focus on sodium batteries and solid state batteries, thin films and electrocatalysis.
