We build cylindrical battery production systems for tabless aluminum shell cells. The lines run automated and work in gigafactory environments.
What does the line actually do? It manufactures tabless cylindrical lithium-ion cells. That's the core application.
We don't use terms like "Industry 4.0-ready" or "unmatched precision" in our spec sheets. Precision depends on your tooling setup and maintenance schedule. The line holds tolerances we can discuss once we know your cell format and volume.
Where do these lines go? EV plants. Energy storage system factories. Power tool manufacturing. Consumer electronics. Renewable energy storage. Backup power systems. Medical devices. Industrial automation. That list looks long, but the line itself doesn't change - it makes cylindrical cells. The application just determines downstream assembly.
If you need a production line for tabless cylindrical cells, this one works. No futuristic claims. Just hardware.

EV Battery Production: Cylindrical Cell Process Flow

Cylindrical Battery Manufacturing Process
Electrode Preparation
Cathode and anode materials are mixed, coated, dried, calendered and slit into electrode sheets.
Cell Assembly
Electrode sheets are processed through winding, shell insertion, welding and sealing processes.
Electrolyte Filling
Electrolyte is injected under controlled environmental conditions before final sealing.
Formation and Aging
Cells undergo formation cycles and storage processes to stabilize electrochemical performance.
Testing and Grading
OCV testing, internal resistance testing, capacity grading and sorting are performed to ensure cell consistency.
