Abstract

A rechargeable battery that comprises a jelly roll type electrode assembly that comprises two electrodes with different polarities and separators for preventing an electrical short between the two electrodes is disclosed. The battery further comprises a case for storing the electrode assembly and electrode tabs that are made of different materials for connecting the two electrodes of the electrode assembly to an external circuit via the case, wherein the thicknesses of the electrode tabs are different. It is possible to reduce the thickness of a protruded part in an outer surface of the jelly roll due to the thinner electrode tabs and to reduce pressure on the activation materials near the protruded part.
