Battery cell and battery module including the same

A battery cell comprising:

• a case accommodating an electrode assembly, the case having a front end, a rear end and side ends, a first surface and a second surface;
• an electrode lead protruding from the case at each of the front end and the rear end of the case;
• a first sealing part formed at both side ends of the case;
• a second sealing part connecting the first sealing part at the front end and the rear end of the case;
• a first edge along the first sealing part;
• a second edge along the second sealing part;
• and
• an insulating member covering the sealing parts and the edges,
• wherein the first sealing part extends to the second edge and is bent in a direction of the first surface of the case so that a first side of the first sealing part is folded against a first side end, and a main portion of the insulating member covers a second side of the first sealing part and the first edge and attaches to the first surface of the case,
• wherein a side surface portion of the insulating member directly contacts the first side of the first sealing part, a first side of the second sealing part and the second edge,
• wherein the main portion and the side surface portion of the insulating member are formed as one piece,
• wherein a bottom edge of the main portion is colinear with a bottom edge of the side surface portion and is below the first sealing part so that the main portion overlies the second surface of the case, and
• wherein a side edge of a portion of the main portion overlying the first surface of the case extends to the second edge.
