Abstract
An electrode assembly manufacturing apparatus includes an electrode sheet supply unit for supplying an electrode sheet on which electrode mixture coating and non-coating portions are formed, a cutting unit at the rear of the supply unit for forming an electrode tab at the electrode sheet, and a lamination unit at the rear of the supply unit and configured to laminate positive and negative electrodes stacked with a separator between them. A cutting unit die supports the electrode sheet and an ultrasonic cutter spaced from the die forms the tab. A cutting line of a cutting edge of the cutter corresponds to a periphery of a unit electrode in a tab forming direction. The cutting and lamination units are on the same line in a continuous process to reduce a necessary space for electrode assembly manufacture and prevent electrode sheet foil deformation and electrode mixture layer damage in the cut section.
