The Battery Electrode Coating Line is a precision manufacturing system designed for applying electrode slurry coatings onto aluminum and copper foil substrates for lithium-ion battery production, supporting both intermittent and continuous coating applications.

Key Features

• Dual coating capability supporting both intermittent and continuous coating types with slot die and comma reverse methods
• Precision coating with ±1.5% surface density accuracy and ±0.5mm position accuracy for top and bottom layers
• Three-zone drying system with 4.5m total length and temperature control from 60-150°C (±3°C)
• Compatible with multiple chemistry types including NCM, LCO, LFP cathodes and graphite anodes
• Processing speeds up to 10m/min with typical operation at 3m/min (adjustable based on slurry conditions)
• Integrated β-ray densimeter for real-time coating density measurement
• Mitsubishi PLC/Servo motor control system for precise operation and automation
