IMPROVED JELLY-ROLL STRUCTURE, AND SECONDARY BATTERY HAVING SAME |
摘要 |
Disclosed herein are a jelly-roll of an improved structure, more particularly a jelly-roll type electrode assembly ("jelly-roll") configured by winding a cathode having a cathode active material coated portion formed at at least one side of a cathode current collector and an anode having an anode active material coated portion formed at at least one side of an anode current collector in a state in which the cathode and the anode are opposite to each other via a separator, wherein a cathode tab mounted at an uncoated portion of the cathode so that the cathode tab is inclined upward at a predetermined angle to a longitudinal direction of the cathode and an anode tab mounted at an uncoated portion of the anode so that the anode tab is inclined upward at a predetermined angle to a longitudinal direction of the anode are located so as to be adjacent to each other to minimize a magnetic field generated by cathode current and anode current during discharge, and the cathode tab and the anode tab are located at the outside end of the jelly-roll after wound, and a secondary battery including the same. |
