Abstract
Official abstract text for this publication.
A secondary battery includes an electrode assembly comprising a first electrode plate, a separator, and a second electrode plate stacked together and folded about a folding part; an outer case surrounding the electrode assembly; and an electrode lead electrically connected to the electrode assembly and extending to the outside of the outer case.
First claim
Opening claim text (preview).
What is claimed is: 1 . A secondary battery comprising: an electrode assembly comprising a first electrode plate, a separator, and a second electrode plate stacked together and folded about a folding part; an outer case surrounding the electrode assembly; and an electrode lead electrically connected to the electrode assembly and extending to the outside of the outer case. 2 . The secondary battery of claim 1 , wherein the electrode assembly is defined by first and second regions about the folding part and wherein the first and second regions are symmetrically formed. 3 . The secondary battery of claim 1 , wherein the electrode assembly is defined by first and second regions about the folding part and wherein the first and second regions are asymmetrically formed. 4 . The secondary battery of claim 1 , wherein the electrode assembly is defined by first and second regions about the folding part and wherein the first region or the second region has an inclined surface formed at its end. 5 . The secondary battery of claim 1 , wherein the electrode assembly is defined by first and second regions about the folding part and wherein areas of the first and second regions are substantially equal to each other. 6 . The secondary battery of claim 1 , wherein the electrode assembly is defined by first and second regions about the folding part and wherein areas of the first and second regions are different from each other. 7 . The secondary battery of claim 1 , wherein the electrode assembly further includes a coupling part formed along the folding part. 8 . The secondary battery of claim 7 , wherein the coupling part is formed on an inner surface of the electrode assembly. 9 . The secondary battery of claim 7 , wherein the coupling part is formed between each of the first electrode plate, the separator, and the second electrode plate. 10 . The secondary battery of claim 7 , wherein the coupling part is formed on an outer surface of the electrode assembly. 11 . The secondary battery of claim 7 , wherein the coupling part comprises polypropylene (PP), polyethylene (PE) or ethylene propylene diene M-class (EPDM) rubber. 12 . The secondary battery of claim 7 , wherein the electrode assembly further includes an additional coupling part formed at a position spaced from the folding part to surround the electrode assembly.
