Brief Description for Prismatic Lithium-ion Batteries with Aluminum Shell

Prismatic aluminum shell batteries are lithium-ion batteries that use an aluminum alloy casing, composed of components such as the cell (positive and negative electrodes, separator), electrolyte, casing, and top cap. They have the following characteristics:

Structural Composition: Includes a top cap, aluminum casing, and jelly roll (rolled electrode assembly), which are sealed into an integrated unit through laser welding.

Working Principle: Based on the migration of lithium ions between the positive and negative electrodes to achieve energy storage and release.

These batteries offer the following advantages:

Lightweight: The thin aluminum casing reduces the overall weight of the battery, making it easy to carry and use.

High Safety: The alloy material of the aluminum casing enhances safety performance, preventing combustion and explosion.

Long Service Life: The stability of the aluminum casing and the non-flammability of the electrolyte extend the battery’s service life.

Compact Structure: The prismatic cell design improves space utilization and is not easily damaged by external forces.

Application Fields: Due to their lightweight, high safety, long life, and compact structure, prismatic aluminum shell batteries have been widely used in the field of new energy, especially in electric vehicles and portable electronic devices.
