A pouch cell is a type of rechargeable lithium-ion battery design that features a flat, flexible, and lightweight structure. Unlike traditional cylindrical or prismatic cells, pouch cells are manufactured by enclosing the battery components, including the electrodes, separator, and electrolyte, within a flexible pouch made of a polymer material. This design offers several advantages, including efficient use of space, reduced weight, and customizable shapes.

Pouch cells are commonly used in a wide range of applications, such as consumer electronics (laptops, smartphones, tablets), electric vehicles (EVs), renewable energy storage systems, and portable medical devices. Their streamlined design allows for better thermal management and can enable higher energy density, resulting in improved overall performance and energy storage capacity. However, pouch cells may be more sensitive to physical damage due to their flexible nature compared to more rigid cell designs. Proper packaging and handling are crucial to ensure the safety and longevity of pouch cell batteries.
