Beschreibung
Zusammenfassung:	A tubular structure for a rectangular battery can for an electric vehicle, which is thin and has very high dimensional accuracy in order to contain as much electrolyte as possible within a limited size, and a method of manufacturing the same are disclosed. In particular, extrusion of a material to a predetermined thickness is performed, and drawing of the extruded material to a thickness desired by a final product is performed. Accordingly, desired thickness uniformity of the final product is maintained.
