Join Peers at the Leading Meeting Place for the Advanced Battery and H/EV Technology Community. 

Meet battery manufacturers, suppliers, engineers, thought leaders and decision-makers for a conference and battery tech expo focused on the latest developments in the advanced battery and automotive industries.

At the Battery Show Europe, Fraunhofer ILT showcases a prototype battery module developed with Team Sonnenwagen Aachen. The module features 30 cylindrical high-performance cells and is part of the thermal management system in their 5^th-generation solar car, designed for a 3,022 km race through the Australian Outback.

A key focus is the laser-based joining of copper busbars (CuSn6) to steel cell terminals — a major challenge in battery manufacturing. For this, Fraunhofer ILT uses the Axialscan Fiber RD-50 with Raylase RDM module for precise beam control and automated focus adjustment, combined with a dual-mode fiber laser from nLight.

The setup ensures clean, reliable, and scalable processing—paving the way for future-ready battery systems in mobility and portable applications.

At The Battery Show Europe, Fraunhofer ILT will present an advancement in battery electrode drying at the Fraunhofer Battery Alliance booth. As part of the IDEEL research project, a hybrid roll-to-roll drying process has been developed that combines laser and convection drying.

This innovation reduces drying time by more than 60  % – while maintaining the same product quality. It saves energy, lowers CO₂ emissions, and improves the cost-effectiveness of battery cell manufacturing. The solution is scalable and suitable for retrofitting into existing production lines.

Fraunhofer ILT develops laser-based sintering processes for the additive manufacturing of functional battery components – such as structured electrodes, thermally conductive cell housings, or current-carrying parts. Using selective laser sintering of metal and ceramic powders, complex geometries, integrated functionalities, and tailored material properties can be created – tool-free, resource-efficient, and with high precision.

A key focus lies on applications in all-solid-state batteries, particularly in processing oxidic ceramic solid electrolytes. These are used as separators and in mixed-cathode architectures.

At The Battery Show Europe, experts from Fraunhofer ILT will explain how laser sintering supports the development of efficient, lightweight, and high-performance battery systems for the next generation.
