Abstract
A rechargeable battery includes: a case; a first electrode assembly accommodated in the case; and second and third electrode assemblies accommodated in the case at positions adjacent to the case with the first electrode assembly being disposed therebetween. The second and third electrode assemblies have thicknesses different from that of the first electrode assembly.
Claims18
A rechargeable battery comprising:
- a case;
- a first electrode assembly accommodated in the case;
- and
- second and third electrode assemblies accommodated in the case at positions adjacent to the case with the first electrode assembly being disposed therebetween,
- wherein the second and third electrode assemblies have thicknesses different from that of the first electrode assembly and wherein the first, second and third electrode assemblies respectively have positive and negative electrode plates and wherein the positive and negative electrode plates of the second and third electrode assemblies are thicker than the positive and negative electrode plates of the first electrode assembly.
