Prismatic Battery Cell

The shape of the square cell is square, and the interior adopts a multi-layer chip structure. Each layer is separated by a lithium-ion battery separator. At the same time, metal or polymer electrodes are added between the sheets to form a positive and negative battery structure.

Compared with cylindrical batteries, square batteries have a larger capacity, and at the same time can use space more efficiently and increase the energy density of batteries. In addition, the structural design of the square cell makes the cell more stable, more shock-resistant and compressive, and thus more durable during use. At present, square batteries are widely used in mobile power supplies, electric vehicles, drones and other fields, and have become an important structure in the battery field.
