Lab Intermittence Coating Machine – Three-Roll Transfer Coater for Battery Electrodes
The Lab Intermittence Coating Machine is a batch-type three-roll transfer coating system designed for precision electrode coating in battery research and development. It can perform both continuous and intermittent coating patterns, making it exceptionally versatile for various substrate coating processes, particularly in the lithium-ion battery industry. This equipment bridges the gap between laboratory experimentation and production-scale coating, delivering coating accuracy and consistency comparable to full-scale manufacturing lines.
Working Principle:
This coater utilizes a three-roll transfer mechanism where coating material is transferred from a applicator roll to the substrate via precision metering rolls. The comma scraper provides precise measurement of coating thickness with an accurate adjustment mechanism. Substrate transport is controlled through tension control systems and an EPC (edge position control) correction device to ensure stable tape transport and precise coating registration.
Key Features:
- Flexible Coating Modes: Switch freely between continuous and intermittent coating patterns.
- High Coating Accuracy: Achieves ±3μm coating thickness precision with comma scraper measurement.
- Precise Substrate Control: Tension control system ensures stable web transport; EPC correction device maintains lateral alignment.
- Efficient Drying System: Hot-air oven with air blowing on both upper and lower sides (1m sections) for uniform, high-quality drying up to 120°C.
- Wide Coating Window: Three-roll transfer design accommodates various material viscosities and coating weights.
- User-Friendly Controls: PLC control with intuitive touch screen operation simplifies parameter setting and process monitoring.
- Optional Solvent Recovery: Can be equipped with solvent recovery and treatment system for environmental compliance.
- Production-Ready Design: Engineered specifically for researchers who need results that translate directly to manufacturing.
Applications:
- Positive and negative electrode coating for:
- Lithium iron phosphate (LFP) batteries
- Lithium cobaltate (LCO) batteries
- Lithium manganate (LMO) batteries
- Other lithium-ion battery chemistries
- Supercapacitor electrode preparation
- Nickel battery electrode coating
- Secondary battery R&D and small-scale trials
