<p>A battery includes a case housing (20) an electrode assembly (10), the case having an opening for receiving the electrode assembly (10), a cap plate (30) combined with the opening so as to close the case, a first insulator (70) on an outer surface of the cap plate (30), an electrode terminal (40) electrically connected to the electrode assembly (10), the electrode terminal (40) extending through a first terminal hole (41) in the cap plate (30) and a second terminal hole (42) in the first insulator (70), a first connection portion (31) that mates the cap plate (30) to the first insulator (70) so as to oppose rotation of the first insulator (70) relative to the cap plate (30), the first connection portion (31) being eccentric with respect to a central line of the first terminal hole (41), and a second connection portion (32) that mates the first insulator (70) to the electrode terminal (40) so as to oppose rotation of the electrode terminal (40) relative to the first insulator (70).</p> |
