Abstract
A method of manufacturing a battery cell is provided. The battery cell has an electrode assembly with a plurality of unit cells that a cathode plate and an anode plate coupled to a separator. A separation sheet or a separator is interposed therebetween. The method includes applying an electrode active material a side of a current collector to manufacture a cathode plate and an anode plate and forming an electrode tab by notching the uncoated portion of the exterior periphery the current collector in the cathode plate and the anode plate where an electrode active material is not coated while forming an aperture. The aperture penetrates through an active material coating layer and the current collector in the coated portion. The method further includes coupling the cathode plate and the anode plate to a separator at a position to allow communication of the apertures to manufacture a unit cell.
