Product DescriptionProduct DescriptionTransfer Coating Machine for Lithium ion Battery Anode and Cathode Electrode Precision Coating1. Equipment functions and parameters1.1 Equipment functions and principlesThe equipment 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.1.2 Equipment process flow chart1.3 Substrate parameterItemCathodeAnodeSubstrateAluminum foilCopper foilWidth (mm)100~330100~330Thickness (μm)9~156~15Note: duringacceptance, the aluminum foil or copper foil used should not be slack, uneventhickness and weight, surface oil, and other phenomena that affect theperformance of coating.1.4 Slurry parameterItemCathodeAnodeMaterialLFP, NCM, ect.GraphiteSolventNMPDI-WaterSolid content(wt%)40~8535~65Slurry specificgravity (g/cm3)1.5~3.01.0~2.0Viscosity(mPa.s)5000 ~ 150003000 ~ 8000Remark: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℃.1.5 Coating parameterItemCathodeAnodeCoating modeContinuous andIntermittent transfer coatingContinuous andIntermittent transfer coatingCoating width(mm)Max 300Max 300Dry thickness ofsingle coating (μm)80 ~ 25080 ~ 250Single sidecoating weight (g/m2)100 ~ 25080 ~ 200Coating speed(m/min)0.5-20.5-3Description:coating speed is related to product characteristics (material system, coatingthickness, solid content, temperature), the maximum coating speed given inthe table can not meet the special coating process requirements.1.6 Equipment specification parameterNoItemContent1Roll width400mm2Mechanical speed(withoutloading)Max 3m/min3UnwindingspecificationRoll diameter:Max. 200mmLoad-bearing:Max. 100kgRollspecification: inner diameter 3 inches (about 76.2mm), length≤450mm.Roll material:metal, ABS plastic, paper.4WindingspecificationRoll diameter:Max. 200mmLoad-bearing:Max. 100kgRollspecification: inner diameter 3 inches (about 76.2mm), length≤450mm.Roll material:metal, ABS plastic, paper.5Oven heatingmodeElectric heating6Ovenconstruction3section x 2 m/section = 6m, single layer7Oven temperatureMax. 140℃2.Coating unitNo.ItemContent1Structural modeOverallvertical plate structure, surface chrome plating treatment.
