The system is capable of processing cylindrical batteries (18650, 21700, 26650, 4680), prismatic batteries, and pouch style batteries. Stations for sorting and welding can easily accommodate different formats and are set up using dedicated fixtures.

When it comes to high-volume, high-speed applications , laser welding is typically chosen. Examples include cylindrical cells with large busbars but more commonly it is used in ultrasonic welding which utilizes a heat source for minimized heat input to thin tabs or heat sensitive cells (e.g. pouch). We are able to incorporate one, or both methods depending on your choice of cell type and tab materials used.

Scanned at the sorting point of the sorting station is the QR code or barcode from each cell. At the sorting station, the same identification number is connected to welding parameters and module assembly data. Finally, during the end-of-line testing process, the module serial number is connected to all historical cell-level data, providing a complete record for safety certification and customer audits.

Customer-defined safety and performance criteria for EV and ESS applications, such as compliance with transportation regulations, electrical safety testing, and verification of performance, can be achieved through EOL testing stations tailored specifically to these specifications; we will collaborate with you to determine what criteria will apply to each of your target markets when designing the testing protocols used at each stage of manufacturing.

For a cylindrical production line, such as standard-sized cylindrical batteries (18650/21700), with laser welded connections and EOL testing, the lead time from signing a contract to factory acceptance is typically 90 to 120 days. For prismatic (or pouch) cell production lines with custom fixturing, the lead time is generally between 120 and 150 days.
