Abstract
Official abstract text for this publication.
A secondary battery having an upper battery assembly including an upper can housing a cap unit having an electrode terminal adapted to electrically connect to an external device and a gasket inserted between the cap unit and one end portion of the upper can for sealing and insulating the cap unit and the upper can. The secondary battery also has a lower battery assembly including a lower can housing an electrode assembly, the electrode assembly having a first electrode, a second electrode, and a separator interposed between the first electrode for preventing a short circuit between the two electrodes. A first electrode tap connects the first electrode to the cap unit and a second electrode tap connects the second electrode to the lower can.
