New materials for energy storage systems — •Margret Wohlfahrt-Mehrens — Zentrum für Sonnenenergie- und Wasserstoff-Forschung, Baden-Württemberg, Ulm

Electrochemical energy storage systems are the key components for mobile applications both in communication systems and in new car concepts as hybrid or full electric vehicles. The rechargeable lithium-ion battery system has become the dominant technology in the global battery market during the last decade. These batteries offer the highest energy density available to date. While commercially used lithium-ion batteries power mostly small devices as cellular phones, portable computers and other mobile electronic equipment, extensive world wide efforts are underway to develop this technology for much more demanding applications such as large batteries for electric vehicles.

The present status of rechargeable lithium-ion batteries, the requirements for various applications and the need for further development will be discussed. The focus of the presentation deals with the materials selection and the materials science principles that underlie the behaviour of advanced electrochemical storage systems. An overview of current electrode materials (anode and cathode) and electrolytes will be given and future research and development needs for new components will be discussed.
