Aluminum foil plays a vital role in new energy batteries, especially as current collectors in lithium-ion cells. A common challenge during battery operation is cell swelling or bulging caused by internal gas buildup.
Laser micro-perforation offers a precise, non-invasive solution. By introducing controlled micro-holes into aluminum foil or functional films, internal gas can escape more efficiently, helping reduce cell expansion and improve battery life.
Key Benefits:
Micron-level precision holes
Non-contact, stress-free processing
High-speed, roll-to-roll compatibility
Better cell consistency and safety
Laser perforation is becoming a critical process in advanced battery manufacturing — enabling safer, longer-lasting, and more efficient energy storage.
