ELECTRODE SHEET COMPRISING NOTCHED PORTION

摘要

The present invention provides an electrode sheet having an electrode active material coated on one surface or both surfaces of a current collector sheet in order to manufacture a plurality of unit electrode plates by cutting, wherein first notched portions are formed on one of the upper and lower sides of the electrode sheet at an interval corresponding to the width of the unit electrode plate, second notched portions corresponding to the first notched portions are formed on the other side thereof, and an upper end cut side for a cutting margin is formed on the second notched portion and is smaller than a lower end cut side.
