Rechargeable battery

1. A rechargeable battery comprising:

a plurality of electrode assemblies each having a first planar surface and a second planar surface substantially opposite to the first planar surface;

a current collecting member electrically connected to the electrode assemblies;

a case housing the electrode assemblies; and

a safety member comprising a first side plate including an insulation film, wherein the insulation film directly contacts the first planar surface of a first electrode assembly of the plurality of electrode assemblies and is spaced from the current collecting member, wherein the first electrode assembly is located at a periphery of the electrode assemblies, a second side plate that contacts the second planar surface of the first electrode assembly, and a connector electrically connecting the first side plate and the second side plate to each other, wherein the first side plate and the second side plate comprise a conductive material.

2. The rechargeable battery of claim 1 , wherein the connector is generally U-shaped to have opposing surfaces.

3. The rechargeable battery of claim 1 , wherein each of the electrode assemblies comprises a first electrode having an uncoated area on which a current collecting member is exposed and wherein the connector is welded to the uncoated area.

4. The rechargeable battery of claim 3 , wherein the first electrode is a negative electrode.

5. The rechargeable battery of claim 1 , wherein each of the electrode assemblies comprises a second electrode and wherein the case is electrically coupled to the second electrode.

6. The rechargeable battery of claim 5 , further comprising a cap plate coupled to the case, an electrode terminal protruding outwardly from the cap plate and being electrically coupled to the second electrode, and a connection member located on the electrode terminal and contacting the cap plate.

7. The rechargeable battery of claim 1 , wherein the first side plate and the second side plate have an insulation film thereon.

8. The rechargeable battery of claim 1 , wherein the safety member engages two electrode assemblies of the plurality of electrode assemblies, each of the two electrode assemblies being located at a periphery of the plurality of electrode assemblies.

9. The rechargeable battery of claim 8 , wherein each of the two electrode assemblies that the safety member engages is located adjacent to an electrode assembly that the safety member does not engage.

10. The rechargeable battery of claim 1 , wherein the connector is connected to one end edge of each of the first side plate and the second side plate.

11. The rechargeable battery of claim 1 , wherein the connector is connected to the top edge or the bottom edge of each of the first side plate and the second side plate.

12. The rechargeable battery of claim 11 , wherein the first side plate or the second side plate further comprises a connection protrusion electrically connected to the electrode assembly.

13. The rechargeable battery of claim 1 , wherein the safety member further comprises a third side plate and a fourth side plate that contact the first planar surface and the second planar surface, respectively, of a second electrode assembly of the electrode assmeblies located at a periphery of the electrode assemblies, and a second connector connecting the third side plate and the fourth side plate to each other, wherein the first side plate and the fourth side plate are located at opposing peripheries of the electrode assemblies, and a third connector connecting the second side plate and the third side plate to each other.

14. The rechargeable battery of claim 1 , wherein the safety member is a single sheet of material.
