Frequently Asked Questions
What is the maximum operating speed of this equipment?
The standard operating speed of the equipment is 10m/min, with a maximum capability of reaching up to 15m/min.
What foil thickness ranges are compatible with this system?
The equipment is designed to handle positive foil thicknesses ranging from 10 to 30 µm and negative foil thicknesses from 6 to 20 µm.
What is the thickness accuracy of the roll plate?
It achieves a thickness accuracy of ±2μm in the normal area and ±3μm in the thinned zone, both maintaining a CPK value of ≥1.33.
What compaction densities can be achieved for positive and negative electrodes?
For positive electrodes, the compaction density is 3.4 g/cm³ to 3.6 g/cm³ (ternary) and 2.2 g/cm³ to 2.6 g/cm³ (Lithium iron). For negative electrodes, the compaction density ranges from 1.5 g/cm³ to 1.7 g/cm³.
What are the final quality and appearance requirements for the plates?
The finished plates must meet strict quality standards, ensuring there are no wrinkles, no damage, no wave edges, no scratches, no cracks, no bulges, and no pollution.
