Lithium-Sulfur Battery: From Materials Development to Production

Published on June 20, 2014

One of the most promising future generation candidates for safe, low-cost and long-lasting high energy density rechargeable energy storage systems is the Lithium-Sulfur (Li-S) battery utilizing sulfur as active material.

Sulfur offers the highest theoretical capacity of all known solid-state cathode materials (1672 Ah kg-1) and is, furthermore, widely abundant in nature, inexpensive as well as environmentally friendly. The wide-range application of Li-S batteries as mobile power supply is highly attractive.
This video discusses new materials development, production technologies, the potential but also the challenges of the development of stable, high energy Lithium-Sulfur Batteries. Furthermore, the important process steps for the production of these batteries are demonstrated.

Kaskel Group | Fraunhofer IWS Dresden, Germany

Prof. Dr. Stefan Kaskel was a group leader at the Max-Planck-Institute for Coal Research (Mülheim a.d.Ruhr) in the department of heterogeneous catalysis until 2004. Since 2004 he is Full Professor for Inorganic Chemistry at Technical University Dresden and since 2008 in parallel head of the department “Chemical Surface and Reaction Technology” at Fraunhofer IWS. He has established a new research focus in Dresden with now appr. 30 scientists (PhD students, post docs) working on the synthesis and characterization of nano-structured inorganic materials. Nano-particle synthesis, integration into polymers, nanocomposites, but also porous materials such as metal-organic frameworks, carbons, and mesoporous oxides are investigated. The group profits from the excellence in materials research in Dresden as represented by a large number of research Institutes. Prof. Dr. S. Kaskel is author of over 160 publications with key aspects of his research activities being metal organic frameworks (MOF), porous carbons and nanocomposites. He is responsible for various research programmes and large scale projects within his research activities.
