Alternative battery concepts beyond “standard Li-ion”: Examples on sodium-ion batteries, solid-state batteries and a surprise on sulfur
报告摘要：The rising demand for rechargeable batteries for electric vehicles and grid storage applications causes a lot of interest on alternatives to “standard Li-ion battery technology”. Major motivations are also directed towards using more low cost components and/or improving safety. Important concepts that are currently studied are sodium-ion batteries, solid state batteries as well as metal-chalcogen batteries (metal-oxygen and metal-sulfur).
This talk gives an overview on the different technologies, materials aspects, chances and challenges. Specific examples will be discussed including high capacity metal/carbon negative electrodes, graphite co-intercalation reactions and metal sulfides for solid state batteries. The recently discovered phenomenon of “sulfur spillover” on carbon materials will be also discussed which may have important consequences for all metal-sulfur batteries based on sulfur/carbon composite 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. His recent publications include Nature Materials, Energy & Environ Sci., Angew. Chem. Int. Ed. etc.
