Abstract:
A rechargeable battery includes: an electrode assembly including a separator between a first electrode and a second electrode each having uncoated regions and coated regions, and in which the separator, the first electrode, and the second electrode are spirally wound; a case that houses the electrode assembly; and a first electrode tab and a second electrode tab to be drawn outside of the case that are respectively coupled to the uncoated regions of the first electrode and the second electrode while maintaining a tab gap between the first electrode tab and the second electrode tab, where the first electrode tab is coupled to a gap uncoated region between the coated regions of the first electrode, and where in a thickness direction of the electrode assembly, in an area facing the first electrode tab, an internal side end uncoated region of the second electrode is located.
