1. A button cell comprising:
an electrode assembly comprising a first electrode, a second electrode, a separator between the first electrode and the second electrode, a first electrode tab coupled to the first electrode, and a second electrode tab coupled to the second electrode;
a case accommodating the electrode assembly and coupled to the first electrode tab; and
a cap assembly sealing an opening in the case, the cap assembly comprising:
a cap plate coupled to the case and covering the opening in the case; and
a terminal plate coupled to the cap plate,
wherein the terminal plate comprises:
a flange portion coupled to and electrically insulated from the cap plate; and
a tab connecting portion protruding from the flange portion toward the electrode assembly and extending through a terminal opening in the cap plate, the tab connecting portion being coupled to the second electrode tab,
wherein a first end of the electrode assembly faces the case, and a second end of the electrode assembly faces the cap plate,
wherein the first electrode tab comprises a first portion connected to the first end of the electrode assembly and a second portion extended from the first portion, and the second portion of the first electrode tab at least partially lies flat between the first end of the electrode assembly and the case, and
wherein the second electrode tab comprises a first portion connected to the second end of the electrode assembly and a second portion extended from the first portion, and the second portion of the second electrode tab at least partially lies flat between the second end of the electrode assembly and the terminal plate.
