Abstract: An insulating case for a secondary battery and a secondary battery having the same, the insulating case having opposing first and second portions. The first portion faces an electrode assembly of the secondary battery and has a first melting point. The second portion faces a cap assembly of the secondary battery and has a second melting point that is higher than the first melting point. The first melting point is approximately the contraction temperature of a separator of the electrode assembly.

Abstract: A secondary battery includes an electrode assembly formed by winding a first electrode plate, a second electrode plate and a separator. The first and second electrode plates are connected to first and second electrode tabs at one side and another side of the electrode assembly, respectively. The separator is interposed between the first and second electrode plates. A can has one opened portion to accommodate the electrode assembly, and a cap assembly seals the opened portion of the can. In the secondary battery, at least one of the first and second electrode tabs includes a drawing portion protruding upward from the first or second electrode plate and a bonding portion formed by bending one region of the drawing portion to be attached to the cap assembly, and a length of the bonding portion is formed longer than a width of the drawing portion.
