OVERVIEW
Product Description
Coating Machine (Double-Deck & Wide-Width)
The equipment is used for coating process during lithium battery manufacturing, which applies sufficiently mixed slurry onto copper foil or aluminum foil in a way that ensures qualified size, surface density and appearance. The coated electrode will be wound into a roll after being dried.
