Battery Cell with Improved Insulative Performance of Electrode Lead and Excellent Productivity on Standardized Structure and Battery Pack Comprising the Same

摘要

The present invention is a battery cell in which the outer circumferential portion of the battery case is sealed by thermal fusion while the electrode assembly is attached to the battery case of the laminate sheet together with the electrolyte, and a pair of electrode leads of the electrode assembly protrude outward from the battery case. , An insulating member is added to each of the electrode leads, and the insulating member is provided in an area of 60% or more compared to a total area of the electrode lead protruding to the outside.
