A prismatic battery cell is a type of lithium-ion battery where the cells are enclosed in a rigid casing, typically with a rectangular shape. This design allows for efficient stacking of multiple cells within a battery module.

roll and stack

There are two types of prismatic cells in terms of manufacturing process:
1. The electrode sheets inside the casing (anode, separator, cathode) are stacked.
2. The electrode sheets are rolled and then flattened.

Each type has its own advantages:
– Stacked prismatic cells can release more energy at once, offering better performance.
– Flattened prismatic cells contain more energy, offering more durability.

Prismatic cells are mainly used in energy storage systems and electric vehicles. Their larger size makes them less suitable for smaller devices like e-bikes and cellphones. Therefore, they are better suited for energy-intensive applications.
