I . Equipment specifications:
1, Substrate thickness: aluminum foil: 0.012--0.030mm copper foil: 0.008-0.030mm
2, Substrate width:aluminum foil:100—280mm copper foil:100—280mm
3, the maximum coating wet thickness:80--400µm (under the viscosity of the slurry allows)
4, the maximum coating width: 280mm, the maximum width of the coating roller: 360mm
5, mechanical transport speed: 0.5-7M / min (maximum speed)
6, coating speed: 0.5-1.5M / min (speed depending on different slurry, this range for reference) (super capacitor can coat faster,
usually can set about 2M/min).
7, Total length of the machine: 1.5 m × 3 section oven+ 1.2 m = 5.7 m

II. Equipment performance
1, coating method: Transferred intermittent coating
Intermittent coating distance: 5-8000mm ± 1mm (according to battery specifications).
2, coating accuracy:
2.1. Dry thickness accuracy error: single-sided cathode: ±2.5μm anode ±2.5μm (cross-section measurement 4-5 points, vertical
section measurement spacing is 100mm).
2.2, the front and back coating alignment error: ≤ ± 1.0mm
2.3, average length error: ≤ ± 1.0mm
2.4, average width error: ≤ ± 1.0mm
Note: The above indicators 1 and 2 should be the best when the slurry conditions (viscosity, particle size, uniformity, etc.)
match the settings of the various parameters of the equipment.

4, tension control: sprocket tension, counterweight constant tension
5, Correction controller accuracy: ±0.01mm; Correction accuracy: ±1mm
6, the operator operates the coating mechanism from the front
