Description

Apparatus for manufacturing electrode assembly and method for manufacturing electrode assembly Technical Field The present disclosure relates to an apparatus for manufacturing an electrode assembly and a method for manufacturing an electrode assembly. Background While primary batteries are not designed to be (re) charged, secondary (also known as rechargeable) batteries are designed to be discharged and recharged. Among secondary batteries, low-capacity secondary batteries are widely used for portable small-sized electronic devices such as smart phones, function phones, notebook computers, digital cameras, and video cameras, and high-capacity secondary batteries are widely used as power sources for driving motors in hybrid vehicles and electric vehicles and for storing electric power (e.g., electric power storage at home and/or utility scale). The secondary battery generally includes an electrode assembly (including a positive electrode and a negative electrode), a case accommodating the electrode assembly, and an electrode terminal connected to the electrode assembly. The electrode assembly may be configured with a separator disposed between the positive electrode plate and the negative electrode plate. The electrode assembly may be manufactured by alternately supplying positive and negative electrode plates with separators therebetween in opposite directions while stacking the separators in a zigzag shape. In this way, the electrode assembly is manufactured in a Z-stack shape, and the stacked structure including the separator, the positive electrode plate, and the negative electrode plate may be distorted or collapsed.
