Equipment Functions and Principles

This single side slot die coating machineis used for precision coating of cathode and anode electrode of lithium-ion batteries. It mainly consists of unwinding part, machine head part, oven part, traction part, winding part, and electric control part. Evenly coat the stirred slurry onto the substrate, ensuring that the size, weight, etc. are within the process range. After drying treatment, roll it up and prepare for the subsequent process.

Base material parameters

Item	Cathode	Anode
Base material	Al foil	Cu foil
Width(mm)	160～320	160-320
Thickness(µm)	8～15	6～12

Remark：The base material used for acceptance should not have any looseness, uneven thickness and weight, surface oil stains or other phenomena that affect the performance of the tape and coating.

Slurry parameters

Item	Cathode	Anode	Tab glue
Material	LFP, NMC ,etc	Graphite	Al2O3、boehmite
Solvent	NMP	DI-Water	NMP
Solids（wt%）	52～65(LFP) 60~76(NMC)	42～50	30～40%
Specific gravity of slurry（g/cm3）	1.5～2.5	1.0～2.0	-
Viscosity（mPa.s）	3500～12000	2500～8000	1000～3000
Remark： 1) Solid content of the same batch of slurry: fluctuation ≤ ±0.5%. 2) The viscosity of the same batch of slurry: fluctuation ≤ ± 500mPa. s, any temperature fluctuation within the 22-30 range ± 2℃. 3) During acceptance, one type of cathode slurry; one type of anodeslurry.

Coating parameters

Item	Cathode	Anode
Coating mode	Continuous, Intermittent, Stripe coating	Continuous, Intermittent, Stripe coating
Coating width(mm)	150-300	150-300
