Demonstrating an Electrode Coater With Your Own Foil and Slurry
A buyer's guide to requiring a demonstration on the buyer's electrode foil and slurry, with practical checks on continuous coating, drying sections, and air supply before acceptance.
Before signing off, require the supplier to demonstrate the lithium-ion battery electrode coater using your own electrode foil and your own cathode or anode slurry, not a generic sample. Ask how the trial will be run continuously and what will be measured across the run.
In the request for quotation, specify the foil width and thickness you will supply and the slurry formulation, and ask whether the demonstration uses your material throughout or only for a short segment. Confirm how the 12 m drying length, arranged as four 3 m sections, will be set for your coating and whether each section can be controlled separately. Ask what compressed air the machine needs at the demonstration point; the catalog reference value is 0.6 MPa, dry and oil-free, so confirm your site can meet it and that the supplier will verify it during the trial.
For acceptance, agree in advance which coated samples are retained, how coating on both cathode and anode runs is judged, and what constitutes a failed demonstration. Include questions on changeover between your materials and on how the supplier will document the trial conditions.
Before requesting a quote, confirm with the supplier that the demonstration will use your foil and slurry, the exact air quality and pressure required, and how the four drying sections will be configured and verified for your process.
