Embodiment Construction

[0043] Hereinafter, a secondary battery according to the present invention and a secondary battery module using the same will be described through exemplary embodiments with reference to the accompanying drawings.

[0044] Figure 5 is a view illustrating the structure of the secondary battery unit cell according to the first embodiment of the present invention.

[0045] see Figure 5 , The secondary battery cell 100 according to the first embodiment of the present invention includes: a battery body 110 in which an electrode assembly is disposed; and an electrode tab 120 extending from each electrode of the electrode assembly to the outside of the battery body 110 .

[0046] Although in Figure 5 Only one electrode tab 120 is illustrated in , but note that the secondary battery unit cell 100 has a positive electrode tab and a negative electrode tab. The electrode sheet 120 may be formed by extending electrodes disposed inside the battery body 110 to the outside, or by conne...
