Electrode Assembly Having Novel Lead-tap Joint Structure and Electrochemical Cell Containing the Same

摘要

The present invention relates to an electrode assembly having a positive electrode / separator / negative electrode structure, wherein each electrode plate constituting the electrode assembly has an electrode tab protruding from one end thereof, to which no active material is applied; The electrode tabs of each electrode plate are coupled to one electrode lead to form an electrode lead-electrode tab joint; And the electrode tab-electrode lead coupling part includes a side-by-side arrangement in which two or more electrode tabs are laterally arranged in a state that they are not overlapped with each other and are coupled to adjacent electrode tabs or electrode leads.
