PURPOSE: A battery cell for a secondary battery is provided to obtain a space for connecting electrode tabs and to simplify the production process thereof by facilitating an assembling process. CONSTITUTION: A battery cell (10) for a secondary battery includes a battery part (11) in which electrode plates are arranged at a constant interval and separators are located between the electrode plates; a case (12) surrounding the battery part; and a positive electrode tab (13) and a negative electrode tab (14) one side of which is electrically connected to the electrode plate and the other side is exposed to the outer side of the battery part. The positive electrode tab and the negative electrode tab are attached to the lamination side of the case. The other side of the positive electrode tab is attached to one side of the case, and the other side of the negative electrode tab is attached to the other side of the case. |
