Abstract:
A battery cell has a structure in which outer peripheral portions of a battery case are sealed by thermal bonding in a state in which an electrode assembly is mounted together with an electrolyte in a battery case made of a laminate sheet, wherein a pair of electrode leads of the electrode assembly protrude outward from the battery case, and an insulating member is attached to each of the electrode leads in an area of at least 60% of a total area of the electrode leads that protrude outwardly.
