Beschreibung
Zusammenfassung:	The invention provides an electrode body for a cylindrical lithium battery, which is formed by winding a laminated body, wherein the laminated body includes a negative electrode sheet, a first separator, a positive electrode sheet, a plurality of anode tabs, and a plurality of cathode tabs, wherein the negative electrode sheet and the positive electrode sheet have negative electrode coating and positive electrode coating, respectively. In the present invention, the positive electrode coating is provided on the positive electrode sheet in a specific configuration to increase the coating area of the positive electrode coating, thereby increasing the capacitance of the electrode body.
