Abstract
A secondary battery includes an electrode assembly, a case accommodating the electrode assembly, and a cap assembly coupled to the case to seal the case, and the case includes a bottom portion, long side portions bent and extended from the bottom portion, a first short side portion bent and extended from the bottom portion, and second short side portions bent and extended from the long side portions, the first short side portion and the second short side portions connected to each other to define a short side portion, and curvatures located between the first short side portion and the second short side portions.
Claims11
A secondary battery comprising:
- an electrode assembly;
- a case accommodating the electrode assembly;
- and
- a cap assembly coupled to the case to seal the case,
- wherein the case comprises a planar bottom portion opposite the cap assembly, long side portions bent and extended from the planar bottom portion to be opposite each other and defining long sides of the case, a first short side portion bent and extended from the planar bottom portion, and second short side portions bent and extended from the long side portions, the first short side portion and the second short side portions connected to each other to define a short side portion, and curvatures located between the first short side portion and the second short side portions, the short side portion and another short side portion being opposite each other and defining short sides of the case, the planar bottom portion being planar from the short side portion to the another short side portion, the curvatures being located at regions where the first short side portion, the second short side portions, and the planar bottom portion meet,
- wherein the curvatures comprise:
- a first curvature located in the first short side portion;
- and
- a second curvature located in each of the second short side portions, and
- wherein the first curvature and the second curvature are in an asymmetric configuration.
