Solid-State Batteries

Advanced equipment for next-generation solid-state battery dry electrode preparation, covering coating, mixing, extrusion and other key processes.

High-Speed Powder Mixer for Dry Electrodes

• Solvent-free processing for dry electrode powder fibrillation and electrolyte raw material mixing, crushing and coating • Significantly reduces manufacturing costs and energy consumption; ultra-high-speed powder mixing advances fibrillation processing speed

Electromagnetic Feeder

• Integrates preheating, leveling and metered conveying to ensure a stable, uniform powder supply for consistent electrode calendering • Tank: SUS304 stainless steel, with a 300-grit mirror-polished interior and 150-grit brushed exterior; a partially hinged hopper lid, bridge-breaking agitator motor (adjustable from 0 to 40 rpm), air hammer and pneumatic butterfly device • Vibrating screen: SUS304 stainless steel, 380V vibration motor with adjustable excitation force; compatible with 6–12 mesh screens • Electromagnetic feeder: amplitude adjusts to material properties and throughput (standard amplitude: 1.2 mm) for precise feeding • Powder preheating: carbon-fiber infrared heating tubes with adjustable temperature and PID control for precision temperature regulation • Powder distributor: quick-clamp design with adjustable distribution width

Twin-Screw Continuous Extruder for Dry Electrodes

• Key advantage: rapid sheet production in 2–5 min, with a simple, efficient process • Simultaneous metered feeding of multiple materials enables continuous production with accuracy up to 0.4% • Independent temperature control for each module and short cleaning and changeover times • Product range: laboratory models 10–100 kg/h; production models 200–1500 kg/h

Solid Electrolyte Coating Machine

• Creates stable interfaces at the source, addressing solid-state battery interface challenges through nanoscale material coating • Key advantage: coating rate above 99%, reducing interfacial impedance and improving overall solid electrolyte system performance • Counter-rotation of the vessel and agitator creates fluidized suspension • Supports gas spraying, liquid spraying and combined gas-liquid spraying • Temperature control accuracy: ±1°C; pressure control accuracy: ±0.1 bar • Product range: laboratory models 2–50 L; production models 100–2000 L

Production-Scale Dual Planetary Mixer

Designed for medium- to large-batch production, the production-scale dual planetary mixer integrates hydraulic lifting and offers working volumes from 300L to 3000L, balancing throughput and slurry quality. Planetary revolution, blade rotation and high-speed dispersion work together with vacuum sealing to prevent contamination and ensure uniform mixing of high-viscosity slurries without dead zones. It is suitable for batch production of lithium battery cathode and anode slurries.

High-Efficiency Inline Mixer

Developed as an upgrade to the PD mixer slurry preparation system, this solution uses separate kneading and dilution-dispersion processes. It enables precise formulation and process control and efficient mixing of all components, ensuring high-quality finished slurry and significantly improving battery performance and cycle life.
