Round Lithium Polymer batteries require a more complex manufacturing process and Lower production volume, as they are typically made by winding the anode, cathode, and separator layers into a cylindrical shape. This process can be more labor-intensive and time-consuming, resulting in higher production costs. Round Lithium Polymer batteries are generally produced in lower volumes than the more common rectangular ones, as they are designed for specific applications and form factors. Lower production volumes can lead to higher per-unit costs due to reduced economies of scale.
