Rechargeable battery

A rechargeable battery comprising:

• an electrode assembly comprising first and second electrodes at opposite sides of a separator and wound about an axis;
• a first terminal coupled to the first electrode through a first tab;
• a second terminal coupled to the second electrode through a second tab;
• a case accommodating the electrode assembly and having first and second openings at opposite ends of the case;
• a first gasket between the first terminal and the case at the first opening, the first gasket sealing the first opening and allowing the first terminal to protrude outside of the case;
• and
• a second gasket between the second terminal and the case at the second opening, the second gasket sealing the second opening and allowing the second terminal to protrude outside of the case,
• wherein the case further comprises a fixing portion at its inner side that protrudes toward the electrode assembly, and
• wherein the fixing portion directly contacts an outermost side of the electrode assembly.
