Pouch cell (soft pack battery) is a type of lithium-ion battery packaging that uses aluminum-plastic composite film (instead of a metal shell) to encapsulate the cell material, featuring high structural flexibility, light weight, and high energy density. It is one of the three major mainstream cell shapes, alongside cylindrical and square batteries, and is widely used in consumer electronics, electric vehicles, and energy storage systems.
Advantages
High energy density: No rigid shell, occupying less space
Lightweight design: Reduces 20%~30% in weight compared to metal shells
Flexible layout: Can be cut into different sizes, compatible with various devices and structures
Optimized thermal management: Large heat dissipation area, easy to design for heat conduction
