  • CRUDE CELL FOR LARGE SECONDARY BATTERY AND PREPARING METHOD THEREOF
    Publication number: 20080160399
    Abstract: The present invention discloses a crude cell for a large secondary battery comprising unit cells alternately stacked in the fold/fold type or a crude cell for a large secondary battery comprising unit cells wound and stacked in the jelly roll type, each unit cell having an anode, a cathode and a separator, in which a polymer film is inserted in the crude cell to support the crude cell. According to the present invention, it is possible to prevent structural distortion caused by external impact and self reaction of the crude cell by firmly supporting the crude cell. Consequently, it is possible to prevent short of the anode and the cathode in the crude cell by electrical connection and to improve interfacial properties of the anode, the cathode and the separator.
