1. A rechargeable battery, comprising: an electrode assembly;a case including a cavity, the electrode assembly being in the cavity;a cap plate coupled with an opening of the case; andan electrode terminal extending through a terminal hole of the cap plate, the electrode terminal being electrically insulated from the cap plate and electrically connected to the electrode assembly, wherein the electrode terminal includes a plate terminal on an external surface of the cap plate and including a screw portion, anda bolt terminal including a first bolt extending at least partially in and being screwed to the screw portion of the plate terminal, the bolt terminal further including a second bolt connected to the first bolt and protruding outside the plate terminal and outside the rechargeable battery, a diameter of the second bolt being less than a diameter of the first bolt, wherein the plate terminal includes a raised spot that is deformed when the first bolt is coupled with the screw portion, the raised spot extending above the first bolt, and wherein the raised spot includes a rivet to further fasten the first bolt and the plate terminal. 2. The rechargeable battery as claimed in claim 1, wherein the screw portion of the plate terminal includes a female thread, andthe first bolt includes a male thread. 3. The rechargeable battery as claimed in claim 2, wherein the plate terminal includesa protrusion extending from a center portion of the screw portion and protruding in a direction parallel to a direction in which the screw portion extends, the protrusion supporting the bolt terminal. 4. The rechargeable battery as claimed in claim 3, wherein the plate terminal includes a space between the protrusion and a sidewall of the screw portion. 5. The rechargeable battery as claimed in claim 3, further including an insulator between the plate terminal and the cap plate, whereina portion of the insulator is under the protrusion and the bolt terminal, the portion of the insulator supporting a side of the protrusion. 6. The rechargeable battery as claimed in claim 1, wherein a top surface of the first bolt and the raised spot of the plate terminal corresponding in position to the top surface include a welding bead. 7. The rechargeable battery as claimed in claim 1, wherein the raised spot further includes a groove below an external surface of the plate terminal. 8. The rechargeable battery as claimed in claim 1, wherein the bolt terminal has a tightening recess on a top surface thereof. 9. The rechargeable battery as claimed in claim 1, wherein the plate terminal and the cap plate include the same material, andthe bolt terminal includes a material different from the material included in the plate terminal. 10. The rechargeable battery as claimed in claim 1, wherein the plate terminal includes aluminum, andthe bolt terminal includes aluminum. 11. The rechargeable battery as claimed in claim 1, wherein the plate terminal includes aluminum, andthe bolt terminal includes stainless steel. 12. A rechargeable battery, comprising: a case;an electrode assembly in the case;a cap plate coupled with the case; andan electrode terminal extending through a terminal hole of the cap plate, the electrode terminal being electrically insulated from the cap plate and electrically connected to the electrode assembly, the electrode terminal including: a plate terminal on an external surface of the cap plate and including a screw portion, anda bolt terminal including a first bolt extending at least partially in and being screwed to the screw portion of the plate terminal, the bolt terminal further including a second bolt connected to the first bolt and protruding outside the plate terminal and outside the rechargeable battery, a diameter of the second bolt being less than a diameter of the first bolt, the plate terminal including a raised spot that is deformed when the first bolt is coupled with the screw portion, the raised spot extending above the first bolt, and the raised spot further including a bus bar receiving groove below an external surface of the plate terminal. 13. A rechargeable battery, comprising: an electrode assembly;a case including a cavity, the electrode assembly being in the cavity;a cap plate coupled with an opening of the case; andan electrode terminal extending through a terminal hole of the cap plate, the electrode terminal being electrically insulated from the cap plate and electrically connected to the electrode assembly, wherein the electrode terminal includes a plate terminal on an external surface of the cap plate and including a screw portion, anda bolt terminal including a first bolt extending at least partially in and being screwed to the screw portion of the plate terminal, the bolt terminal further including a second bolt connected to the first bolt and protruding outside the plate terminal and outside the rechargeable battery, a diameter of the second bolt being less than a diameter of the first bolt, wherein the plate terminal includes a raised spot that is deformed when the first bolt is coupled with the screw portion, the raised spot extending above the first bolt.
