fgrthv17.jpg

Principle and Application

● Advanced Multi-Measurement System: Efficiently measures both wet and dry thickness of foils and electrodes, catering to diverse industrial needs.
● Innovative Motion Control System: Achieves exceptional tension control accuracy of ≤± 1N, ensuring stable foil operation even at high speeds for superior performance.
● Micron-Level Precision: Features a state-of-the-art closed-loop adjustment mechanism that maintains an optimal gap between the coating nozzle and the back roller.
● Consistent Wind Speed Uniformity: Each individual nozzle maintains a lateral wind speed uniformity of ≤ ± 1.5%, while the wind speed uniformity across each oven is ≤± 3%, enhancing process reliability.
● Optimal Temperature Control: Each oven ensures temperature uniformity of ≤ ± 1.5%, critical for achieving high-quality coatings in manufacturing.
Discover top-quality solutions from China, where our expert suppliers and factory deliver advanced technologies tailored for your manufacturing needs.

    Frequently Asked Questions
    Q What battery electrode materials are supported by this equipment?
    This system is designed for mainstream battery chemistries including Lithium Cobaltate (LCO), Ternary materials (NMC/NCA), Lithium Iron Phosphate (LFP), and Lithium Manganate (LMO) for both cathode and anode slurry coating.
    Q How is coating accuracy maintained across both sides?
    The machine incorporates precision slot die technology and real-time surface density monitoring to maintain a tight density tolerance of ≤±1% across both sides.
    Q What is the operational line speed of this slot die coater?
    The equipment operates stably up to a maximum continuous speed of 100 m/min, providing high production efficiency for battery manufacturing lines.
    Q What surface density ranges can be achieved for cathode and anode?
    The equipment supports a single-side surface density range of 100–300 g/m² for positive electrodes and 100–250 g/m² for negative electrodes, with a minimum dry film thickness of ≥4 µm.
    Q What visual quality standards are guaranteed during coating?
    The finished electrode meets strict industrial standards with zero defects: no wrinkles, no damage, no wavy edges, no scratches, no cracking, no bulging, and no contamination.
