The Differences Between Cylindrical Batteries and Prismatic Batteries

Cylindrical and prismatic batteries are two primary packaging forms of lithium-ion batteries. They are widely used in various fields such as electric vehicles, portable electronic devices, and energy storage systems. Although their basic working principles are similar, there are some significant differences in design, structure, performance, and applications.

1. Packaging Shape

Cylindrical Batteries: Typically refer to batteries with a cylindrical shape, such as the commonly seen 18650 battery (18mm in diameter and 65mm in length).
Prismatic Batteries: These batteries have a rectangular or square shape and come in various sizes, which can be customized according to application requirements.
