Roll to Roll Continuous Doctor Blade Coating Machine for Battery Electrode Making Lithium Battery Machine
This equipment is mainly used for lithium battery electrode in the production
process slurry drying process, is mainly used in the experiments ,using this technology
can replace the original production of hand-scraped pulp, oven drying operations, and improve the uniformity and scrape pulp drying efficiency is indispensable equipment for mass production.

2) Substrate width: Aluminum foil: 300mm , Copper foil: 300mm
3) Maximum wet coating thickness: 80--400µm (under the condition of slurry viscosity permitting)
4) The maximum width of coating: 300mm, the maximum width of coating roller: 360mm
5) Mechanical traveling speed: 0.5-8M/min (maximum speed)
6) Coating speed: 0.5-1.0M/min (different according to different slurry)
7) The total length of the oven: 1 meter oven (integrated)
2. Equipment performance
1 ) Coating method: Continuous coating
2) Coating precision:
2.1. Accuracy error of dry thickness: single-sided cathode: ±2.5µm , anode ±2.5µm (cross-sectional measurement 4-5 points, vertical section measurement spacing is 100mm).
2.2. Alignment error of front and back coating: ≤±1.0mm
2.3. Average length error: ≤±1.0mm
2.4. Average width error: ≤±1.0mm
Note: The first and second indicators above should have the best effect when the slurry conditions (viscosity, particle size, uniformity, etc.) match the settings of the equipment parameters.
