Battery Manufacturing EquipmentPrismatic EV Cell Automatic Winding Machine
LEAD's Prismatic EV Cell Automatic Winding Machine winds multi-tab and full-tab prismatic cells 120–350 mm wide, 80–410 mm high and 10–40 mm thick. It lists 3,000 mm/s design line speed, 8 pieces per minute with 16 m electrodes, ±3% servo tension and optional turret, CCD and Hi-Pot modules.
Cell sizes, speed and options
LEAD's page describes a winder for multi-tab and full-tab prismatic EV cells. It covers finished cells 120–350 mm wide, 80–410 mm high and 10–40 mm thick. These are cell dimensions; ask LEAD for the electrode widths they imply and whether your particular combination of sizes, especially at the extremes, can run.
The maximum design line speed is 3,000 mm/s. A separate capacity entry gives 8 pieces per minute with a 16 m electrode. The two figures measure different things. Ask for accepted output at your electrode length, cell geometry and handling sequence, and avoid converting web speed straight into cells per minute.
LEAD lists servo tension control with ±3% fluctuation and web guiding. Optional modules include two- or three-station turrets, automatic roll change, CCD inspection, Hi-Pot checks and barcode labelling. Since these are options, the quote must state which ones you will receive.
| Parameter | Published value | Record status |
|---|---|---|
| Winding tension tolerance | ±3% | known |
| Wound cell height | 80..410 mm | known |
| Wound cell width | 120..350 mm | known |
Catalogue values apply to the configuration and test method the maker states. Ask for the values that apply to your configuration.

Follow the web through a changeover at acceptance
Send electrode and separator drawings with tab layout, edge condition and the overhang you need. Agree where alignment is measured, how a defect is caught and whether the affected core is rejected or held. Look at startup and steady-running results separately.
Ask for a demonstration of roll change, restart and unloading with the options you are buying. If downstream handling needs a cell identifier, agree where the label goes on and how winding and inspection records follow it. Treat the production-data interface as its own deliverable, since the barcode option only covers labelling.

Documents to request from LEAD
The government report on LEAD's stock listing and the official portfolio describe the company and what it sells. Ask for winding trial results on your materials, equipment acceptance records from comparable projects and the safety and installation scope for your order. Base ratings on those documents rather than on customer or market claims.
LEAD's profile describes the turnkey line this winder can sit in, and the coating width and slitting decisions upstream fix the electrode it receives; the slitting category lists the machines that make that electrode.

Questions that change the purchase
| Decision | What the catalogue says | Next step |
|---|---|---|
| Does the reference rate fit this cell? | The page gives eight pieces per minute with a sixteen-metre electrode. | Send your electrode length and ask for a sustained trial on your format. |
| What proves winding quality? | The page gives line speed and tension figures but no alignment results. | Define alignment checks, reject criteria and recovery from splices or web faults. |
Equipment questions
Does 3,000 mm/s guarantee 8 PPM for any cell?
No. LEAD's 8 PPM figure assumes a 16 m electrode. Agree the full cycle and how good cells are counted for your design.
Source s2Are every CCD, Hi-Pot and roll-change module standard?
No. LEAD lists them as configurable options. Ask for a machine and software configuration schedule before you judge the offer.
