Roll to Roll Battery Electrode Coating Machine For Lithium ion Cells Electrode Preparation (TOB-JS400-2)

Overview

Model TOB-JS400-2 by TOB NEW ENERGY is a roll-to-roll battery electrode coating machine for precision coating of cathode and anode electrodes of lithium-ion batteries. Product origin: China; shipping port: XIAMEN; order (moq): 1set; Payment: L/C,T/T. The machine consists of unwinding part, machine head part, oven part, traction part, winding part, and electric control part and evenly coats stirred slurry onto the substrate, dries the coating, then winds the material for subsequent processing. Roll surface width is 400mm and mechanical speed (unloaded) is Max.5m/min. Base material parameters: cathode uses Al foil with width 160-320 mm and thickness 8-15 μm; anode uses Cu foil with width 160-320 mm and thickness 6-12 μm. Coating parameters include modes Continuous, Intermittent, and Stripe coating for both cathode and anode, coating width 150-300 mm, dry thickness of single-sided coating 70-350 μm (cathode) and 60-350 μm (anode), single coating weight 30-250 g/㎡ (cathode) and 20-200 g/㎡ (anode), and coating speed 0.5~1 m/min (cathode) and 0.5~1.5 m/min (anode). Unwinding and winding specifications: roll diameter Max φ300mm, load bearing Max.100kg, inner diameter 3 inches (approximately 76.2mm), length 400 ± 3mm, roll material metal or ABS plastic. Oven uses electrical heating with structure 1 section × 2m/section = 2m, single layer, and oven temperature Max.150℃. Overall dimensions approximately L(4.3m) × W(2.1m) × H(2.5m). Power requirements: Three phase AC380V ± 10%, 50Hz, protective grounding; equipment installed power 25KW. Compressed air requirements: pressure ≥ 0.6MPa with ±1% fluctuation, consumption 5m3/h, interface pipe Φ12mm. Environmental requirements for the coating part: temperature 25 ± 5℃, relative humidity 10%~30% RCH, cleanliness Class 100000. Total weight approximately 1.6tons; recommended flooring cement or terrazzo with flatness ±5mm/㎡ and bearing capacity ≥500 kg/㎡. Oven air volume: maximum exhaust at 140℃ 1500 m3/h (positive electrode) and 1500 m3/h (negative electrode); maximum fresh air at 60℃ 1100 m3/h (positive electrode) and 1100 m3/h (negative electrode). The TOB-JS400-2 is used for precision coating of cathode and anode electrodes of lithium-ion batteries in a roll-to-roll workflow, applying stirred slurry to foil substrates, drying the coating, and winding the coated material for subsequent processing. Supported coating methods explicitly listed are Comma Blade (only for continuous coating), Roll Coating (Transfer) for continuous and intermittent coating, and Slot Die coating; slot die capability is offered as a customization option. A lab-oriented roll-to-roll battery electrode coating application is indicated by the referenced “Roll to Roll Lab Battery Electrode Coating Machine” materials and video.
