1. A rechargeable battery comprising: an electrode assembly comprising a positive electrode, a negative electrode, and a separator between the positive electrode and the negative electrode;a case housing the electrode assembly;a cap assembly coupled to the case;a terminal;a lead tab electrically coupling the terminal to the electrode assembly; anda spacer adapted to absorb an impact or vibration, the spacer being coupled to the lead tab and being at least partially located between the lead tab and the case, wherein the lead tab has an anti-vibration groove or hole adapted to receive a latch of the spacer. 2. The rechargeable battery of claim 1, wherein the lead tab comprises a side plate having the anti-vibration groove or hole. 3. The rechargeable battery of claim 2, wherein the side plate has a vent opening configured to allow gas generated by the electrode assembly to exit the case. 4. The rechargeable battery of claim 2, wherein the side plate has a first surface and a second surface, and wherein the spacer is inserted into the anti-vibration groove or hole such that first and second portions of the spacer extend in opposite directions from the first surface and the second surface, respectively. 5. The rechargeable battery of claim 1, wherein the spacer comprises at least one first support between the case and the lead tab, and at least one second support between the lead tab and the electrode assembly. 6. The rechargeable battery of claim 5, wherein the at least one first support is cylindrically shaped and extends toward an inner side wall of the case. 7. The rechargeable battery of claim 5, wherein the at least one second support is received by the anti-vibration groove or hole. 8. The rechargeable battery of claim 5, wherein the spacer further comprises a plurality of first supports located between the case and the lead tab, and a plurality of second supports located between the lead tab and the electrode assembly. 9. The rechargeable battery of claim 8, wherein the spacer further comprises a base plate engaging each of the plurality of first supports and each of the plurality of second supports. 10. The rechargeable battery of claim 9, wherein the base plate comprises the latch. 11. The rechargeable battery of claim 10, wherein the anti-vibration groove or hole of the lead tab is adapted to engage the latch, and wherein the latch has a wedge shape. 12. The rechargeable battery of claim 1, wherein the spacer comprises an insulating material. 13. The rechargeable battery of claim 1, wherein the spacer comprises an elastic material. 14. The rechargeable battery of claim 13, wherein the elastic material is a polymer. 15. The rechargeable battery of claim 1, wherein the lead tab comprises: a side plate having the anti-vibration groove or hole for receiving the spacer; anda terminal junction part extending substantially orthogonally from a first end of the side plate and having a terminal opening adapted to receive the terminal. 16. The rechargeable battery of claim 1, wherein the spacer contacts an inner surface of the case. 17. The rechargeable battery of claim 1, wherein the spacer contacts an inner surface of the case opposite the electrode assembly. 18. A rechargeable battery comprising: an electrode assembly comprising a positive electrode, a negative electrode, and a separator between the positive electrode and the negative electrode;a case housing the electrode assembly;a cap assembly coupled to the case;a terminal;a lead tab electrically coupling the terminal to the electrode assembly; anda spacer adapted to absorb an impact or vibration, the spacer including a latch to stably support the spacer against the lead tab, wherein the lead tab has an anti-vibration groove or hole adapted to receive the latch of the spacer.
