RWTH PEM Chair and HYNN Collaborate to Advance E-Mobility Manufacturing
RWTH Aachen University’s Chair of Production Engineering of E-Mobility Components (PEM) and its spin-off, PEM Motion, collaborate with Chinese plant manufacturer HYNN to advance prototype testing for battery cell production at PEM’s Aachen headquarters. This partnership aims to enhance research and educational opportunities by integrating practical systems into teaching, thus enriching student learning experiences. Additionally, PEM is expanding its long-standing collaboration with BST, a Bielefeld-based mechanical engineering specialist, to focus on innovative production technologies for batteries, fuel cells, and electrolyzers. These collaborations, which have been ongoing since 2017, include projects such as the ‘Fit4E-Mobility’ workshop, installations in the PEM eLab, and a consortium project with BMW focused on fuel cell industrialization. They have also cooperated with the Fraunhofer Research Centre for Battery Cell Production and the German Engineering Federation (VDMA) since 2022. These efforts aim to industrialize production processes and foster innovation in e-mobility components manufacturing.

Open-Source Lithium-Ion Battery Database Launched by Fraunhofer ISI
The “BetterBat” research project, backed by the German Federal Ministry of Education and Research, has launched an open-source database featuring detailed information on over 300 lithium-ion battery cells from various manufacturers. This database, primarily derived from official datasheets, includes critical technical specifications such as size, weight, capacity, and energy density. It aims to aid industry and research institutions in benchmarking and selecting suitable battery cells for diverse applications. It emphasizes the importance of systematic and application-specific requirements in battery technology development. Future updates plan to expand the database with more comprehensive data and analysis tools.

Have a look into the Open Source database: GitHub – https://github.com/TUMFTM/TechnoEconomicCellSelection
Have you already looked into it? Is there a use case where you can benefit from the database?
German researchers are working on better sodium batteries
The “NaKlaR” research project is focussing on sodium batteries. The researchers’ aim is to make this type of battery more electrochemically efficient and sustainable. The project is pursuing the development of a sodium battery based on protected cathode materials, aqueous production of the electrodes and hydrolysis-resistant electrolytes. At the same time, this battery should have an output that is approximately equivalent to today’s reference cells. The aim is also to achieve recyclability: The plan is to produce cells with at least 25 per cent recycled electrode material without any significant loss of performance.
Besides the University of Würzburg, the Karlsruhe Institute of Technology and the Helmholtz Institute Ulm, the Fraunhofer ISC is also part of the project team. On the industrial side, E-lyte Innovations GmbH, Carl Padberg Zentrifugenbau (CEPA), CellCircle UG and Leclanché are involved.
More information on the project: https://www.uni-wuerzburg.de/en/news-and-events/news/detail/news/naklar-batteries/
What specific advancements in cathode material protection and hydrolysis-resistant electrolytes do you believe will be most critical for improving the electrochemical efficiency and sustainability of sodium batteries? Please, share your technical insights and other opinions.

CATL is working on a more powerful sodium-ion battery:
CATL is developing the second generation of its sodium-ion batteries, which are designed to offer an energy density of 200 Wh/kg. Mid-2021 CATL was one of the first battery manufacturers to present its own sodium-ion battery. The first generation had an energy density of 160 Wh/kg according to the information available at the time. A second generation with 200 Wh/kg has now been announced. By comparison, lithium-ion batteries with liquid electrolyte are maxed out at around 350 Wh/kg.

Given the advancements in energy density from 160 Wh/kg to 200 Wh/kg in CATL’s sodium-ion batteries, what are the key technical challenges that need to be addressed to close the gap with lithium-ion batteries further? Please share your insights and potential solutions.
What do you think about the potential of sodium batteries? Please comment!
