    摘要: The present invention relates to a battery cell which is housed in a variable state cell case in which a pole assembly having an anode/separating film/cathode laminate configuration is impregnated with an electrolytic solution. The pole assembly and the cell case are curved together in the same direction at both their ends relative to their central parts in vertical cross section in the axial direction, and they provide a battery cell having a configuration whereby they are curved in a single plane. When such a battery cell is installed in a device having a curved appearance in a single plane or is installed in a location which is curved in a single plane on the inside of a device, there are advantages in that it is efficient, can minimise waste in the space required because of the intimately fined configuration, and it allows the development of devices which have an aesthetically pleasing appearance and which have a diversity of design tailored to consumer preferences.

    摘要: Disclosed herein is a secondary battery constructed in a structure in which pluralities of electrode tabs, protruding from an electrode assembly, are connected to corresponding electrode leads, and the electrode assembly is mounted in a receiving part, wherein a battery case is multi-formed, such that the battery case presses the upper end of the electrode assembly by a predetermined width, thereby preventing the upward movement of the electrode assembly, mounted in the receiving part, at the upper end space region of the receiving part, where the electrode assembly is spaced apart from the upper end of the receiving part, for the connection between the electrode tabs and the corresponding electrode leads, during the repetitive charge and discharge of the battery. Consequently, it is possible to prevent the occurrence of a short circuit of the battery due to external impacts, such as the dropping of the battery, and to prevent the occurrence of an internal short circuit of the battery due to the expansion of the battery case caused by the repetitive charge and discharge of the battery, whereby the safety of the secondary battery is improved.
