Publicly-funded research projects

The project pursues the goal of the Green Battery funding priority of establishing a sustainable and closed material cycle for battery materials over the entire life cycle and enabling recyclable battery cell production. Reliable quality assurance of battery cells plays a central role in this. X-ray-based computed tomography (CT) is used as a method for non-destructive material testing, precisely because of its ability to make internal structures visible in three dimensions.

Sodium instead of lithium – the “SIB:DE” project is looking into promising battery tech based on sodium ions and how it can be integrated into existing production lines. Learn more about the “SIB:DE” project here.

In the »Safe.SIB« project, research is being conducted on durable sodium-ion batteries for use as stationary energy storage. They are intended to help balance fluctuations in the power grid and ensure a reliable emergency power supply. At the same time, the technology offers the potential to strengthen Europe’s resource and technological sovereignty while significantly reducing raw material costs compared to lithium-ion batteries.

The »EXINOS2« project advances the technology readiness level of an innovative machine concept for the flexible and continuous stacking of battery cells. The aim is to optimize this critical stacking process in terms of flexibility, throughput, and footprint, and to test the system under real production conditions.

The "REVAMP" project offers a new approach to recycling used automotive batteries after their so-called "first life".

The FORWARD cooperation project, “Forecasting and Optimizing of Welding for Advanced Production of Battery Cells,” addresses the urgent need for intelligent and digitized battery cell manufacturing. The project focuses on the critical step of cell conductor welding in cell assembly.

How can battery charging times for stationary energy storage systems be significantly reduced? In the “SchnelleZelle” project, Fraunhofer FFB is working with partners from science and industry to improve the fast-charging capability of lithium-ion batteries.

How can the “time to market” in battery technology be sustainably shortened? In the KOOP project, we are developing a highly cooperative scaling process that promotes the systematic exchange of personnel, data and management between innovators and the Fraunhofer FFB. Our focus is on energy-efficient trajectory mixing and aqueous processing of hard carbon anodes for sodium-ion batteries.

Learn more about how Fraunhofer FFB is driving the scaling and validation of an advanced structured calendaring system in the joint project. By developing new process and analysis technologies, it enables precise monitoring and control of the calendaring process at speeds of up to 25 m/min. The goal is to systematically optimize electrode quality and further process the structured electrodes into pouch cells to compare their electrochemical properties with conventionally manufactured cells.
