Description

Apparatus for manufacturing an electrode assembly and method for manufacturing the same The present disclosure relates to an apparatus for manufacturing an electrode assembly and a method for manufacturing the same. Unlike primary batteries, which cannot be recharged, secondary batteries are batteries capable of both charging and discharging. Low-capacity secondary batteries are used in small portable electronic devices such as smartphones, feature phones, laptop computers, digital cameras, and camcorders, while high-capacity secondary batteries are widely used as power sources for motor drive systems and energy storage batteries in hybrid and electric vehicles. Such secondary batteries include an electrode assembly consisting of a positive electrode and a negative electrode, a case housing the assembly, and electrode terminals connected to the electrode assembly. An electrode assembly can be constructed by placing a separator between an anode plate and a cathode plate. The electrode assembly can be manufactured by stacking the separator in a zigzag pattern and alternately supplying the anode and cathode plates between the separator from opposite directions. In this manner, when the electrode assembly is manufactured in a Z-stack form, problems may arise where the stacked state of the separator, anode plate, and cathode plate becomes distorted or collapses as they are stacked.
