Precision Extrusion Single Side Slot Die Coating Machine For Battery Production 




1. Process Flow

The base material of the polar plate placed on the unwinding device enters the unwinding tension system after automatic correction, and enters the coating head after adjusting the unwinding tension. The polar plate is coated according to the setting procedure of the coating system. The coated wet electrode piece enters the oven and is dried by hot air. The tension of the dried pole piece is adjusted by the tension system, and the winding speed is controlled to synchronize with the coating speed. The pole piece is automatically rectified by the rectifying system to keep it in the set position, and is wound by the winding device.

Remarks

1

Normal Speed of Coating

≤24m/min

Normal coating speed is related to material system, coating thickness and solid content

2

Coating Speed Accuracy Error

≤0.1m/min

 

3

Coating Width

≤650mm

 

4

Coating Length (Single Piece)

≤2500mm

 

5

Coating Machine Speed

40m/min

 

6

Overall Length of Coater

≤43m

It has a great relationship with configuration

7

Equipment Air Pressure

0.60.8 MPa

Dry and free of impurities

8

Single Side Coating Dry Thickness Error

Li(NiCoMn)O2,

LiFePO4,

Cobalt±2μ

(Mn±2μ)

Edge, head and tail 8mm are excluded

9

Double Side Coating Dry Thickness Error

Li(NiCoMn)O2,

LiFePO4,

Cobalt±3.0μm

(Mn±3μ)

 

10

±1.5%

Measurement method

(Fig. B)

11

Minimum Coating Length

20mm

 

12

Minimum Length Dimension of Single Pole Piece

50mm

(One coating plus gap)

13

Minimum Length Dimension of Single Double Segment Pole Piece

100mm

(Two coatings plus gap)

14

Single Side Thickness Error of Electrode Head and Tail

-10μm~ +5μm

 

15

Interval Coating Minimum Gap

10mm

With the coating speed, the faster the speed, the greater the minimum gap.
