The difference between polymer cells and traditional lithium-ion batteries lies in the production process. Lithium batteries are wound and have a softer volume, while polymers are stacked and have a harder shape. For polymers and lithium batteries of the same volume, polymers have a larger capacity, about 30% higher, and are safer with a lower risk of explosion. Due to the requirements of shape and size, it is necessary to fold the sides of the cell to ensure that the finished battery can be made into a certain shape for subsequent installation and other steps.
