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.
