<p>A battery pack according to present invention comprises a battery cell having negative electrode and positive electrode and supplying charged power; a protection circuit module(PCM) for preventing the battery cell from being over-charged or over-discharged; a negative electrode plate coupled to the negative electrode; a holder coupled to the upper portion of the battery cell and having a first opening provided in a portion where the holder is coupled to the electrode of the battery cell; a cover case provided to receive the PCM, the negative electrode plate, and the holder therein and coupled to the battery cell; and a connection plate for electrically connecting the positive electrode and the PCM. By the present invention, the battery pack has such a structure that can prevent the PCM and the positive electrode plate from moving freely. Therefore, the mechanical strength of it can be enhanced.</p> |
