PURPOSE: A battery cell is provided to prevent degradation in durability caused by deterioration and to increase charge and/or discharge efficiency. CONSTITUTION: A battery cell (100) comprises a battery unit (120) which contains an anode plate (121); a cathode plate (122); a partition wall; an anode tab (130) which is extended from the anode plate; a cathode tab (140) which is extended from a cathode plate; and a case (110) which seals containing the battery unit and in which the anode tab and the cathode tab are protruded to outside. More than two of the anode tabs and/or the cathode tab are formed in the battery cell. The battery cell has the anode tab and the cathode tab protruded on 'more than two of sides selected among the front, the back, the left, and the right direction of a case'. |
