Pouch-shaped secondary battery sealing apparatus and pouch-shaped secondary battery manufacturing method
12562416 · 2026-02-24 · ·

The present invention relates to a pouch-shaped secondary battery sealing apparatus and a pouch-shaped secondary battery manufacturing method capable of radiating an infrared laser to a sealed portion in an overlapping state, whereby it is possible to increase sealing force, to prevent occurrence of wrinkles, and to reduce sealing time when forming a sealed portion of a pouch-shaped secondary battery case.
