Abstract

A method for cutting an electrode tab protruding from an electrode includes supporting the one surface of the electrode tab; and cutting, by a cutting knife, the electrode tab by pressing the electrode tab so that a pressure is applied to the other surface of the electrode tab. The cutting knife ensures the angle formed between the cutting knife and the electrode tab is an acute angle. An electrode tab according to the above method includes one surface that is flat and the other surface parallel to the one surface. The electrode tab has a cut surface having one end extending to the one surface and the other end extending to the other surface. The cut surface is provided as an inclined surface so that an angle between the cut surface and one of the one surface and the other surface is defined as an acute angle.
