Battery Manufacturing EquipmentSingle-layer extrusion electrode coater
KATOP's single-layer extrusion electrode coater runs continuous slot-die coating. It lists an 800 mm roller face with 650 mm coating width, 50 m/min mechanical and 40 m/min coating speed, ±0.3 mm dimensional and ±1% coat-weight accuracy, and 5–30 mg/cm² loading.
By KATOP
Three different limits
KATOP's page describes continuous slot-die extrusion coating. It lists a maximum roller face of 800 mm, a maximum coating width of 650 mm, a maximum mechanical speed of 50 m/min and a maximum coating speed of 40 m/min. The extra roller width carries the web and adds no coated area, and the web can travel at 50 m/min while coating tops out at 40 m/min.
The catalogue also gives coating dimensional accuracy within ±0.3 mm, coat-weight accuracy of ±1% and areal loading of 5–30 mg/cm². Before you write these tolerances into a purchase agreement, agree the slurry, speed, sampling positions and how start and stop zones are handled.
| Parameter | Published value | Record status |
|---|---|---|
| Coating width | Maximum 650 mm | known |
| Coating speed | Maximum 40 m/min | known |
| Roller face width | Maximum 800 mm | known |
Catalogue values apply to the configuration and test method the maker states. Ask for the values that apply to your configuration.

Test the recipe and the drying duty together
Send foil thickness, slurry formulation, solids, viscosity and target loading. Ask which die, metering set-up and dryer KATOP proposes for that recipe. An even cross-web weight says nothing about whether the coating is dry enough, and good drying at one speed may fail at another.
For patterned coating, agree the geometry and the usable edges. If two-sided registration matters, ask which extra pass or configuration provides it, since single-layer describes only part of a two-sided process. Log roll identity, trial speed, measured weight distribution and the first good section after a restart.

Define what is in the package
List the coater, dryer, exhaust and solvent recovery, inspection and roll handling as separate items in the quotation. Ask who commissions each interface and which consumables or recipes you must supply. Request current certificates, material trial results and installation references for your review.

A recipe-linked trial with a restart
Compare offers on the same substrate, slurry, coated width and dry coating-weight target. Ask each supplier to state the operating recipe and drying endpoint behind its speed figure. Keep the mechanical speed in the specification table, and base the purchase on accepted coating output.
In the trial, keep cross-web profiles and labelled samples from the steady run. Log start-up, stop and restart losses separately so steady output does not hide transition waste. Check how the package measures coating variation and which adjustments the operator makes. Get drawings of the chosen head and oven with maintenance access and utility needs. With these in hand, the catalogue model becomes a configuration you can compare, and the trial then measures how it performs.

Cell-making interfaces in the offer
KATOP's company introduction gives business background, and any cell-making equipment in the offer needs its own scope. Ask the supplier to define the incoming material condition, transfer and reject handling, and stacking inspection. Set accepted output for that package separately from the coating equipment.

Tie drying and solvent handling to the coating trial
Ask KATOP which feed system, slot die, oven sections, exhaust and solvent-handling items the offer includes. Mark where the coater's responsibility ends and where your facility systems or other contractors begin. The catalogue's top coating speed becomes an acceptance point only once a recipe and drying condition are attached to it.
Keep the sampling plan linked to usable coating width, areal loading and how restart material is treated. The Liyang quality-management decision gives company background and holds no trial data for this coater, so take your acceptance figures from the quoted configuration.
Questions that change the purchase
| Decision | What the catalogue says | Next step |
|---|---|---|
| Which speed is relevant to output? | The page lists 50 m/min mechanical speed and 40 m/min coating speed. | Ask for a trial at your slurry, coating weight and drying endpoint. |
| Which width is usable? | The page lists an 800 mm roller face and 650 mm coating width. | Send your coated-edge requirements and confirm head and web dimensions. |
Equipment questions
Can the machine coat at 50 m/min?
KATOP lists 50 m/min as mechanical speed and 40 m/min as maximum coating speed. Take 40 m/min as the catalogue coating limit, then confirm the accepted speed on your recipe.
Source s2Does the 800 mm roller give an 800 mm electrode coating?
No. The maximum coating width is 650 mm. Ask for edge margins and pattern dimensions for your product before estimating usable electrode area.
