Intermittent Transfer Battery Electrode Coating Machine Coater for EV Electric Vehicle Power Lithium Battery Making Machine
Product Overview
For battery electrode coating ,can be intermittent coating and continuous coating process .
Coating process :
The substrate placed on the unwinding device is automatically corrected and then enters the
floating roll tension system, and the unwinding tension is adjusted to enter the coating head, and the slurry is coated according to the setting procedure of the coating system. The coated wet electrode enters the oven and is dried by hot air. Then the dried electrode is tensioned by a tensioning system while controlling the winding speed to synchronize it with the coating speed. The electrode is automatically corrected by the correcting system to maintain it in the center position, and is wound up by the winding device.
