Matthews Engineering, a division of Matthews International Corporation, and hs-tumbler GmbH announced a cooperation to advance trajectory mixing technologies tailored for dry battery electrode (DBE) manufacturing. The joint development targets scalable powder preparation and higher calender throughput for next-generation, DBE production systems.

This collaboration brings together Matthews' deep expertise in precision engineering and advanced calendar systems with hs-tumbler's proprietary trajectory mixing technology, aimed at enabling consistent, high-quality powder preparation upstream of electrode calendering and lamination. Dry electrode manufacturing continues to gain momentum from cell makers, automotive OEMs and research institutions seeking solvent-free, energy-efficient production solutions, including for next-generation battery chemistries.

Trajectory mixing applies a controlled Lissajous-type motion within a sealed container to produce highly homogeneous dry-electrode powder mixtures. In a single processing step, the method achieves uniform binder distribution and controlled fibrillation, thereby replacing multiple conventional dry-mixing and conditioning stages. The technology enables high feed uniformity and improved electrode mouldability, while simultaneously reducing mixer wear, metal contamination, and active-material particle damage. In addition, the enclosed process significantly minimizes dust exposure, providing clear operational and safety advantages for battery cell manufacturing and R&D lines.

Early development efforts under the cooperation have shown promising indications that trajectory-mixed DBE powders can support increased calender throughput at elevated line speeds while maintaining quality parameters of the dry electrode sheet.  Further, cell assembly using trajectory-mixed powders, show the potential for improved productivity in dry electrode workflows.

"This partnership advances our shared vision of enabling next-generation battery manufacturing for our customers," said Brandon Babe, President, Matthews Engineering. "By combining Matthews' advanced calendering and process expertise with hs-tumbler's innovative trajectory mixing, we aim to provide the scalable upstream processing foundation that DBE production requires, while further enhancing our intellectual property platform."
