Pouch type battery cell
The POUCH CELL is relatively lightweight and flexible because it does not use metal enclosures, and boasts a packaging efficiency of 90 to 90%. A laser system equipped with SMART FOCUSING and VISION is required to maximize volume without affecting the lamination structure of the anode and cathode due to pouch sealing.

Features
AXIAL POUCH
The battery terminals for the positive and negative tabs are placed opposite each other. There is research showing that it has better heat management performance than Radial type. Compared to Radial, the distance between processing points is longer, but distance travel time can be minimized with an ultra-high speed scanner.
RADIAL POUCH
The two terminals for the positive and negative electrodes are placed in the same direction. Since the module design is more compact than the Axial type, it is possible to work a little faster. The free laser path design performs excellent heterogeneous welding regardless of the tab design and terminal layout.
NO WRINKLE
During the sealing process, the POUCH on both sides must not wrinkle as it is squeezed. The load applied to the cell during the integration process into packs and modules can press wrinkles and cause tearing and electrolyte leakage.

NO MARK
Visible marks on the exterior are by no means just an aesthetic flaw. Even small marks can gradually grow as POUCH heats up and expands, and can damage the electrical insulation of the pouch by causing pinholes in the inner plastic film.

Contactless targeting
Before POCKET SEALING, it is very important to accurately calculate the spacing and cell position of the tabs protruding out of the pouch. Many welding facilities have no choice but to perform position search and welding with separate devices, which increases production time. Unlike conventional methods, non-contact laser systems are equipped with vision to quickly perform position search and work simultaneously.

Sustainable Processes
Various cell designs are being improved for efficient storage of electrical energy, such as power density and extended lifetime. Lasers can respond flexibly to new customer needs without changing the structure of the facility. Furthermore, if you consider LIFE CYCLE for battery reuse, a laser other than thermal glue or lead oxide would be the best choice.

Quality improvement
Various elements, such as springs to prevent expansion and heat release valves, are added to the inside of the pouch to enhance battery stability. In order to maintain the electrical insulation of ANODE, CATHODE, and SEPERATOR, the elements must be properly wrapped without excessive compression. The laser maintains a uniform distribution of energy, prevents shape distortion, and controls internal damage with a minimum range of thermal effects.
