Prismatic cells are a type of battery cell characterized by their rectangular shape, which allows for efficient use of space and easy stacking in battery packs. They are commonly used in various applications, including electric vehicles, portable electronics, and energy storage systems. Prismatic cells are known for their robustness and good thermal management properties. They can be found in lithium-ion, lithium polymer, and other battery chemistries. In electric vehicles, prismatic cells are often chosen for their ability to be configured into compact, lightweight battery packs that can fit into the vehicle's design. In portable electronics, such as smartphones and laptops, they provide a balance between energy density and form factor.
