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

0.6～0.8 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

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.

16

Accuracy Error of Coating Length

±1.0 mm

Within 3000mm

17

Overlap Error of Front and Back Coating

±0.5 mm

18

Overlap Error of Front and Back Coating Edge

±0.5 mm

19

Edge Uniformity Error of Winding

± 1 mm
