Storage systems for electrical energy represent one of the most important components in the restructuring of the global energy industry and also play a central role in many other fields of application, such as electromobility, due to their universal applicability.
The current state of the art is the lithium-ion battery. It is available in a wide variety of shapes and sizes. However, the currently available electrochemical storage systems are perceived as unsatisfactory for many applications in terms of important requirements (energy content, low-temperature behavior, cost-effectiveness, etc.).
Work is underway worldwide to reduce or even overcome these deficiencies through the ongoing optimization of existing systems or through the development of electrochemical storage devices with new material combinations, such as Li/S. The transfer of the new storage concepts obtained in this way to industrial production involves major technical and economic challenges.
The Research Center for Applied Battery Technology Schleswig-Holstein (FAB-SH) of Fraunhofer ISIT specializes in the field of energy storage development. The manufacturing technology is characterized by a very high flexibility and is thus an ideal technological platform for the production of prototypes and small series for a wide range of applications, such as traction and stationary energy storage. Furthermore, FAB-SH has extensive experience in the scaling of manufacturing processes and the characterization of cells of different chemistry and design. These competences enable the development of customized storage solutions and furthermore complete systems with the hardware and software necessary for control.
Fraunhofer ISIT participates in the Fraunhofer Research Institution for Battery Cell Production FFB, a large project funded by the Federal Ministry of Education and Research (BMBF) with the aim to support industrial partners and customers in the implementation of new battery cell concepts and the development of associated manufacturing processes.
The Power400 project is concerned with the development of a high-performance charging system with integrated buffer storage. The project is supported by the European Union (European Regional Development Fund). The goal of the project is to design the charging stations in such a way that a large number of electric vehicles can be charged quickly at the same time without destabilizing the public power grid.
