Frequently Asked Questions
The standard operating speed of the equipment is 10 meters per minute, with a maximum capability of reaching up to 15 meters per minute depending on the material and production setup.
It supports positive foils ranging from 10 to 30 µm and negative foils from 6 to 20 µm. The overall compatible pole plate thickness ranges from 50 to 300 µm.
The machine achieves a high roll plate thickness accuracy of ±2μm in the normal area and ±3μm in the thinned zone. Both zones maintain a process capability index (CPK) of ≥1.33.
For positive electrodes, the compaction density ranges from 3.4 g/cm³ to 3.6 g/cm³ (ternary materials) and 2.2 g/cm³ to 2.6 g/cm³ (lithium iron phosphate). For negative electrodes, it achieves a compaction density of 1.5 g/cm³ to 1.7 g/cm³.
The output must be completely flawless. The appearance requirement strictly dictates that there must be no wrinkles, no damage, no wave edges, no scratches, no cracks, no bulges, and no pollution on the processed plates.
The equipment guarantees a precise winding alignment tolerance of within ±0.5mm to ensure consistent coil winding performance.
