For decades, EAS Batteries has stood for innovation and technological excellence in cell and battery manufacturing. As an active partner in national research and funding projects, EAS’s dedicated team of experts continuously advances the optimization of the entire value chain – from electrode development and cell production to data-driven quality assessment in module and pack assembly.
Research and industrial implementation go hand in hand at EAS Batteries. At the beginning of this year, the three-year research project High-E-Life was successfully completed, with EAS serving as consortium leader and playing a key role in advancing the performance of large-format cylin-drical lithium-ion cells through laser-structured electrode design. At the same time, EAS joined the ongoing project QUGAPP, which aims to set new standards in quality and sustainability as-sessment through software-based data prediction. The objective is to further optimize cell and battery manufacturing processes, minimize scrap rates, and sustainably enhance product quality.
#High-E-Life – Laser-Structured Electrodes for Higher Energy Density
Launched in January 2023, the High-E-Life project was coordinated by EAS together with the Karlsruher Institut für Technologie and EdgeWave. The goal was to significantly increase the performance of large-format cylindrical lithium-ion cells. For the first time, concepts of laser structuring were successfully transferred to large-format wound cells and applied, among others, to LFP-based cells.
Using a specially developed ultrashort-pulse laser, several hundred meters of electrode material were structured in a roll-to-roll process.
This structuring technology increased the energy densi-ty of 46120-format LFP cylindrical cells and significantly improved fast-charging capability. The successful transfer of laser structuring concepts demonstrates strong potential for a new genera-tion of high-performance, long-lasting high-energy cells—an important step toward industrial scalability and technological differentiation.
The project had a total volume of €2.1 million and was funded with €1.3 million by the Bundesministerium für Forschung, Technologie und Raumfahrt (BMFTR) from resources of the Climate and Transformation Fund.
Building on these results, EAS has also been involved since 2023 as an application partner in the transfer project “Process Scaling of Laser-Structured Thick-Film Electrodes in High-Performance Li-Ion Batteries (Hi-LiB).” The aim is to scale laser structuring technology through the development of an industrial plant concept. In particular, improving optical beam guidance for multi-beam laser processing of large-area electrodes at web speeds of up to 30 m/min marks a key milestone. This demonstrates that the results and innovations are consistently pursued beyond the original project’s completion—further strengthening the performance of EAS cylindrical cells.

#QUGAPP – Quality from the very beginning
While High-E-Life further strengthened the technological foundation for higher-performance cells, the QUGAPP project focuses on data-driven quality assurance and sustainability assessment. Since January 1, 2026, EAS has been a partner in this collaborative project running until the end of 2026, implemented under the SynBatt funding directive of the Bundesministerium für Forschung, Technologie und Raumfahrt. Under the consortium leadership of IconPro, industry and research partners are working to establish so-called “Predictive Quality Gates.”
The goal is to predict test results for cells and battery packs at an early stage, reduce scrap, opti-mize testing scope, and derive sustainability indicators directly from process and quality data. EAS contributes extensive manufacturing data, process expertise, and pilot applications, supporting the implementation of the developed software solutions in industrial practice. By integrating predictive quality models and data-based sustainability assessments, EAS strengthens process stability, reduces scrap, and increases transparency across the entire value chain.
#EAS as research partner
The company’s position, as demonstrated by these two projects, is clear: EAS not only enhances the performance of its products but also increases transparency, process stability, and resource efficiency in cell manufacturing through scientific collaboration in these and similar initiatives.
“Research for us does not mean isolated development, but tangible improvements to our industrial reality. With High-E-Life, we have expanded the performance limits of our cells – with QUGAPP, we are creating the data-driven foundation to systematically optimize quality and sustainability,” says Michael Deutmeyer, Managing Director of EAS Batteries.
With this approach, EAS Batteries underscores its commitment to continuously combining innovation, production excellence, and sustainability—actively shaping the next generation of high-performance battery cells.
