Battery cell and battery module

A battery cell, comprising:

• an electrode body including a plurality of layered structures layered one on another, each including a positive electrode, a negative electrode, and a separator disposed between the positive electrode and the negative electrode;
• and
• a battery cell case that hermetically encloses the electrode body inside the battery cell case,
• wherein:
• each of the positive electrode and the negative electrode includes a current collector and a mix that includes an active material and that is coated on a surface of the current collector,
• at least one of the current collector in the positive electrode or the current collector in the negative electrode has, on a peripheral portion of a surface thereof, an uncoated portion at which the mix is not coated, and
• a current collector of which a distance from a surface of the battery cell case is greatest among current collectors each having an uncoated portion has a first uncoated portion, and the first uncoated portion extends to outside of the battery cell case, thereby forming a first exposed portion.
