Transfer Coating Machine Functions and Principles

The battery electrode transfer coating machine is used for lithium ion battery anode and cathode electrode precision coating, which is mainly composed of unwinding part, the head part, the oven part, the traction part, the winding part and the electric control part. The mixed slurry is uniformly coated on the substrate to ensure that the size and weight are within the process range. After drying, it is rolled up to prepare for the later process.

Transfer Coating Machine Process Flow Chart

Substrate unwinding → Tension stabilization → Transfer coating → Drying → Tension stabilization → Tension → Rewinding and correcting

Substrate Parameter

Item	Cathode	Anode
Substrate	Aluminum foil	Copper foil
Width (mm)	100～330	100～330
Thickness (µm)	9～15	4～15
Note: during acceptance, the aluminum foil or copper foil used should not be slack, uneven thickness and weight, surface oil, and other phenomena that affect the performance of coating.

Slurry parameter

Item	Cathode	Anode
Material	LFP, NCM, ect.	Graphite
Solvent	NMP	DI-Water
Solid content (wt%)	40～85	35～65
Slurry specific gravity (g/cm3)	1.5～3.0	1.0～2.0
Viscosity (mPa.s)	5000 ~ 15000	3000 ~ 8000
Remark: 1)The solid content of the same batch of slurry: fluctuation ≤±0.5%. 2)The viscosity of the same batch of slurry: fluctuation ≤±500mPa.s, 25±2℃.

Coating parameter

Item	Cathode	Anode
Coating mode	Continuous and Intermittent transfer coating	Continuous and Intermittent transfer coating
Coating width (mm)	Max 300	Max 300
Dry thickness of single coating (µm)	80 ~ 250	80 ~ 250
Single side coating weight (g/m2)	100 ~ 250	80 ~ 200
Coating speed (m/min)	0.5-2	0.5-3
Description: coating speed is related to product characteristics (material system, coating thickness, solid content, temperature), the maximum coating speed given in the table can not meet the special coating process requirements.
