A secondary battery includes an electrode assembly having a diameter of L2, a can housing the electrode assembly and at least one fixing portion extending from an inner wall of the can toward an outer surface of the electrode assembly. L1 is defined as the shortest distance between two portions of the inner wall of the can which substantially directly oppose each other. The distance of L2 subtracted from L1 may be in the range from -0.12 mm to 0.10 mm. |
