Types of LiFePO4 Battery Cells

Prismatic LiFePO4 Batteries

Prismatic cells came out in the early 1990s. Prismatic cells are a type of lithium-ion battery design that uses a rectangular or square-shaped pouch instead of a cylindrical or button-shaped cell. The pouch is made of a thin, flexible, lightweight aluminum or copper-plated foil, and the electrodes are coated with a lithium-ion conductive material. Prismatic cells are mainly used in energy storage systems and electric vehicles, as they can save space, weight, and cost compared to cylindrical cells.

Pros:

Prismatic lithium battery can save space, weight and cost by by increasing the packing density and allowing for flexible design.

Prismatic LiFePO4 batterhy have high reliability and energy efficiency, as they use a thin, flexible, lightweight aluminum or copper-plated foil as the pouch

Easy to expand and customize according to the size and power needs of the product.

Cons:

They have lower energy density and shorter cycle life than cylindrical cells, as they use more inactive materials and have lower volumetric efficiency.

They have higher risk of swelling, leaking, or rupturing, as they have less mechanical strength and stability than cylindrical cells.

They have higher manufacturing costs and complexity, as they have less standardized processes and require more advanced materials and technologies.

Pouch LiFePO4 Batteries

Pouch cells have a thin and flexible shape and a soft aluminum laminate film casing. Pouch LiFePO4 battery offers higher energy density than other types of LiFePO4 cells but are still highly reliable and long-lasting.

Cylindrical LiFePO4 Batteries

Cylindrical lithium-ion battery is a lithium ion battery with cylindrical shape, so called cylindrical lithium-ion battery.
