Safe electromobility with long ranges - that should be possible with the new solid-state batteries from the Karlsruhe Institute of Technology (KIT). They have large storage capacities, fast charging times and no flammable, liquid electrolytes. The technology could one day also serve as an energy store for renewable energies. In the “Festbatt” competence cluster, KIT is currently researching batteries together with 13 other scientific institutions.
Solid material electrolytes
The solid-state battery is intended to help promote sustainable energy technology. Scientists are currently working on a mix of very different batteries that are tailored for use in electric vehicles or storage in industrial applications and private households. In addition to the already established lithium-ion batteries with liquid electrolytes inside the battery, research based on electrolytes made of solid materials is also increasingly becoming the focus of research.
BOOK TIP Based on the current state of the art, the "Battery World" specialist book provides basic knowledge of battery technology and offers an overview of the development, construction and use of batteries. The book also gives an insight into potential and future development trends.
"Solid-state batteries of this type are fire-safe and could enable larger storage capacities and faster charging processes in the future," says Professor Helmut Ehrenberg from the Institute for Applied Materials (IAM) at KIT. This type of battery therefore has the potential to enable safe electromobility with long ranges as well as to be used stationary. For example, solid-state batteries could also be used as effective storage for electricity from private photovoltaic systems. In order to achieve these goals, there is still a considerable need for research in the solid-state battery.

Understand how it works in detail
This is where the new cluster of expertise for solid-state batteries “Festbatt” comes into play. It includes all research institutions in Germany that are relevant to the subject of solid electrolytes and solid-state batteries - including universities and research centers from the Helmholtz Association and the Fraunhofer Society. The KIT is involved with several institutes and receives funding from the BMBF in the amount of EUR 3.95 million in the first project phase over three years. The aim of "Festbatt" is to develop basic knowledge for solid-state batteries and to understand their functioning in detail, to describe it scientifically and to develop functional prototypes. With the competence cluster, however, the foundation stone for the establishment and sustainable development of an internationally leading,competitive battery cell production in Germany.
“Festbatt” consists of five joint projects: three material and two method platforms. The focus of the first project phase is the reproducible production of suitable solid electrolytes. Professor Ellen Ivers-Tiffée, who works on the competence cluster, explains: “The selection of compatible materials is essential for the later cell design. The electrochemical characterization carried out by us provides the most important material-specific parameters and thus enables the selection of high-performance material combinations."
The new competence cluster complements the activities of KIT in the field of electrochemical energy storage research. Starting with the development of new types of electrode materials for lithium and post-lithium technologies, up to the effective production of large-format cells on an industrial scale and their combination and regulation in battery packs, all relevant aspects of battery development are mapped within the "KIT Battery Technology Center". In the "Center for Electrochemical Energy Storage Ulm & Karlsruhe" founded in this year, in which the KIT is significantly involved, the focus of the research lies not only on the development of lithium and post-lithium technologies, but also on fire-safe and resource-saving alternatives such as Redox flow cell,on fuel cells as energy converters and especially on the training of young scientists.
In order to make electric mobility suitable for the masses, better battery technologies are needed, among other things. A research project wants to make solid-state batteries fit for electromobility
In order to be able to use electricity from regenerative energies consistently, large stationary energy stores are required. A research project is currently investigating how used electric bus batteries can be used: In a multi-family residential complex in G /u00f6teborg, batteries from Volvo electric buses are given a new life by recycling them as stationary solar energy storage devices
Solid state batteries are considered the future of storage technologies. A Chinese start-up has now started to produce in small series
L /u00fctze Transportation has expanded its Microcompact series with a new semiconductor relay. It switches loads up to 7 A in rail traffic
Lithium-ion batteries still have 70% to 80% of their performance when they have had their day in the electric car. What else these batteries could do in secondary recycling and how they can contribute so significantly to the energy turnaround is shown at the Hannover Messe Energy
