The present invention relates to a pressurizing tray which is equipped with a roller to pressurize a battery cell. According to the present invention, the pressurizing tray comprises: a frame which accommodates a plurality of battery cells disposed in an interior space; and a plurality of pressurizing jigs which are disposed between neighboring battery cells to pressurize the battery cells by moving in the horizontal direction. The pressurizing tray comprises a number of rollers to additionally pressurize the battery cells when the pressurizing of the battery cell by the pressurizing jigs is completed. According to the present invention, the gas generated from the battery cells in an activating process can be completely removed, thereby improving stability, durability and service life of a secondary battery. |
