A pouch cell battery is a type of lithium-ion battery that features a flexible, flat pouch-shaped design. It’s also known as a soft pack battery cell. The pouch is made up of a layer of aluminum-coated plastic film. Only two tabs stick out, each welded to current collectors in the pouch. These highly conductive tabs carry out the positive and negative connector tabs and allow to get the electric energy out of the pouch cell.

Eliminating the metal enclosure reduces the weight of these cells. They are widely used in various applications, including automotive, consumer electronics, and energy storage. The pouch cell is one of the three major form factors of lithium-ion batteries, the other two being cylindrical and prismatic.

There are LiFePO4 pouch cell, NMC pouch cell, lithium polymer pouch cell etc.
