inline surface cleaning for lithium-ion battery production
In high-performance battery manufacturing, even microscopic contamination can reduce battery quality, increase resistance, and lead to unstable cell performance. The BMe CLEAN laser cleaning system removes particles, oxide layers, oils, and process residues from battery components before the subsequent assembly processes.
Designed for inline integration into lithium-ion battery production lines, the system enables precise, contact-free surface preparation for copper, aluminum, and coated battery materials. The BMe CLEAN supports prismatic, cylindric and pouch cell types.
Insufficient surface preparation may lead to unstable welding processes, poor energy coupling, increased spatter, and inconsistent weld quality.Â

why laser cleaning matters in battery production
improve process reliability through cleaning before welding
Surface contamination is one of the most common causes of:
- poor weld seams
- unstable electrical connections
- increased contact resistance
- scrap and rework
- reduced battery performance
Inline laser cleaning improves process stability before:
- laser welding
- bonding
- tab joining
- busbar assembly
- adhesive dispensing
a highly controllable process
Compared to mechanical or chemical cleaning methods, laser cleaning is a dry, contactless, and highly controllable process that supports modern battery manufacturing requirements.
