Matthews Engineering and hs-tumbler Join Forces to Enable High-Speed Dry Electrode Manufacturing Through Trajectory Mixing
Cooperation combines trajectory mixing and calendering expertise to improve powder preparation, throughput and process consistency for dry battery electrode manufacturing.
Joint development aims to support scalable, solvent-free DBE production with more homogeneous powder mixing, higher line speeds and improved operational performance.
PITTSBURGH and QUAKENBRÜCK, Germany, March 19, 2026 /PRNewswire/ — Matthews Engineering, a division of Matthews International Corporation (NASDAQ: MATW), and hs-tumbler GmbH today 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.
Brandon Babe, President, Matthews Engineering, said:
This partnership advances our shared vision of enabling next-generation battery manufacturing for our customers,
“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.”
