摘要： Disclosed herein is a mandrel configured to be used in a winding process for manufacturing a jelly roll type electrode assembly using a long sheet type stack of a cathode/separator/anode structure, wherein the mandrel is oval in a section perpendicular to a rotational central axis of the mandrel, a length ratio of a major axis to a minor axis of the mandrel being 1.5 or more, and a tilt of an outer side of the mandrel is continuously changed from an end of the minor axis of the mandrel to an end of the major axis of the mandrel in the section perpendicular to the rotational central axis of the mandrel.

摘要： Disclosed herein is a mandrel configured to be used in a winding process for manufacturing a jelly roll type electrode assembly using a long sheet type stack of a cathode/separator/anode structure, wherein the mandrel is oval in a section perpendicular to a rotational central axis of the mandrel and is divided into a first mandrel part located at one side of a central region of the mandrel, in which an end of the sheet type stack is fixedly fitted, and a second mandrel part located at the other side of the central region of the mandrel, and the first mandrel part and the second mandrel part each include a main body part having a region in which the sheet type stack is fitted in an engaged state and an exchange part, detachably mounted to the main body part, having an end of a major axis of the mandrel.
