International Battery Seminar & Exhibit 2023

Fraunhofer ISIT will present the following topics at the International Battery Seminar & Exhibit 2023:

FAB-SH: Customized battery solutions from northern Germany.

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 necessary hardware and software for control.

Dry coating

Dry coating process for battery electrodes: environmentally friendly, cost-efficient, space- and energy-saving.

The fabrication of heavy-duty electrodes is a promising approach to increase the energy density of Li-ion batteries, as they have a favorable ratio between active and inactive materials. However, modern tape casting processes with relatively high solvent content are limited in terms of layer thickness and drying process, which is associated with undesirable effects such as binder migration. Therefore, advanced processes for electrode fabrication are urgently needed.

Fraunhofer ISIT has developed a dry coating process that does not require any solvents at all. Drying the coated electrode slurry is an energy-intensive process. It also requires a large amount of space, as long drying distances are necessary for an optimal process result. The dry coating process developed by Fraunhofer ISIT eliminates the need for solvents. In addition, higher loadings are possible that exceed the range of conventional electrodes. This leads to significant cost savings and is more environmentally friendly.

High power cell

High-current lithium-based batteries are commonly used in compact and portable equipment where downtime or unplanned maintenance does not pose financial risks. However, in a growing number of industrial markets, battery storage must be based on safe and reliable technologies to ensure long life and meet energy needs regardless of weather conditions and over the lifetime of the equipment.

The ultra-high performance batteries developed in our laboratory, which can be manufactured with a discharge rate of up to 60 C, can be considered a turning point in terms of safety, reliability and performance. Our batteries are based on different cell chemistries (classical, specialized) and are used in numerous industries.
