In the industrialization of solid-state batteries, electrode manufacturing has always been a core constraining mass production. Faced with challenges such as the sensitivity of solid electrolyte materials, difficulties in solid-solid interface control, and the high energy consumption of traditional wet processes, Manst has reconfigured the manufacturing process from its roots, focusing on dry process electrode technology. The company has introduced its self-developed "Dry Powder Handling System" and "Dry Multi-Roll Double-Sided Film Formation and Lamination System," driving the transition of solid-state batteries from the laboratory to large-scale production through technological innovation.
Dry Powder Handling System: From Raw Materials to Fibrous Granulation, Ensuring Safety and Stability
The Dry Powder Handling System is responsible for the entire process from raw powder materials to fibrous granulation, including powder feeding, metering, mixing and pre-fibrillation, twin-screw fibrillation, crushing, and sieving. Its core innovation lies in the self-developed all-ceramic dry twin-screw fibrillation equipment:
The use of all-ceramic barrel liners and threaded elements fundamentally prevents the introduction of metal impurities, enhancing battery safety and cycle life.
The ceramic material offers extremely high wear resistance, with equipment service life ≥18,000 hours, significantly reducing maintenance frequency and costs.
A dual-end support structure effectively suppresses shaft deflection deformation, with pilot line processing capacity reaching 150L/h, ensuring good scalability from small-scale testing to mass production.
Precise shear force is applied within the 19°C phase transition temperature window of PTFE binders, enabling the construction of a nanoscale fibrous network and forming a uniform and stable electrode skeleton.
This system not only addresses the risk of micro-short circuits caused by metal contamination but also lays a solid foundation for subsequent high-quality film formation.
Dry Multi-Roll Double-Sided Film Formation and Lamination System: Key to Mass Production of High-Consistency Electrodes
The quality of the film formation process directly determines the consistency of electrode performance. Manst's system integrates three innovative technologies—pre-film formation mechanism, double-sided synchronous film formation, and multi-roll parallel calendering—significantly improving film formation precision and efficiency:
The Dry Multi-Roll Double-Sided Film Formation and Lamination System significantly enhances film formation precision and efficiency through multiple innovative technologies. The system uses a pre-film formation mechanism to pre-compress the powder material, achieving continuous, quantitative, and stable feeding, effectively improving compaction density and film thickness uniformity.
The 14-roll double-sided synchronous film formation process breaks through the limitations of traditional single-sided film formation, enabling simultaneous formation of double-sided electrodes with film thickness fluctuations controlled within ±3μm, far exceeding industry standards.
The multi-roll calendering system supports precise adjustment of gaps, pressure, and temperature, enabling multi-stage calendering and meeting diverse film formation requirements. With a device width of 800mm and a maximum line speed of 50m/min, it ensures efficient production while maintaining quality.
The system integrates unwinding, tension control, lamination, and winding functions, avoiding film deformation and wrinkles, and improving overall electrode consistency. It provides reliable support for the mass production of high-energy-density solid-state batteries.
The synergistic cooperation between Manst's Dry Powder Handling System and Multi-Roll Double-Sided Film Formation and Lamination System brings revolutionary breakthroughs to solid-state battery electrode manufacturing. The seamless integration of the two systems enables efficient integrated production from raw materials to electrodes, not only avoiding pollution risks associated with traditional processes but also setting new benchmarks in energy consumption, efficiency, and consistency.
In the future, Manst will continue to deepen innovation in dry process technology, refine technical details, and enhance system compatibility and stability, providing more efficient, economical, and reliable electrode manufacturing solutions for global solid-state battery production.
