<P>PROBLEM TO BE SOLVED: To provide an electrode assembly with interelectrode resistance difference of a tab-lead connection part minimized, and an electrochemical cell equipped with the same. <P>SOLUTION: In a stack type or a stack/folding type electrode assembly of a cathode/separating film/anode structure, respective electrode plates constituting the electrode assembly have tabs (electrode tabs) protruded which are not coated with an active material, and these electrode tabs are electrically coupled with one electrode lead, a plurality of electrode tabs are coupled respectively on the upper face and the lower face of the electrode lead at the connection part, so that the interelectrode resistance difference at an electrode lead-electrode tab connection part can be minimized. <P>COPYRIGHT: (C)2011,JPO&INPIT |
