Abstract:
A battery module according to the present invention includes rechargeable batteries that include a first terminal and a second terminal which protrude outward, the first terminal including differentiation portions formed of an indentation or a protruding portion to differentiate the first terminal from the second terminal; and connection members that electrically connect the rechargeable batteries, fixed to the first and second terminals of adjacent rechargeable batteries, including verification portions which fit the differentiation portions so as to improve assemblability and minimize contact resistance.
Abstract:
A secondary battery having a current interrupt device (CID) between a negative current collecting plate and a case of the secondary battery. The secondary battery includes: an electrode assembly including a positive electrode, a separator, and a negative electrode; a case housing the electrode assembly; a cap assembly coupled to the case for sealing the case; a positive current collecting plate connected to the positive electrode and the cap assembly; an insulator in the case adjacent an end plate of the case; and a negative current collecting plate connected to the negative electrode and the end plate of the case, the end plate being curved convexly toward an inner cavity of the case.
Abstract:
A battery includes a case housing an electrode assembly, the case having an opening for receiving the electrode assembly, a cap plate combined with the opening so as to close the case, a first insulator on an outer surface of the cap plate, an electrode terminal electrically connected to the electrode assembly, the electrode terminal extending through a first terminal hole in the cap plate and a second terminal hole in the first insulator, a first connection portion that mates the cap plate to the first insulator so as to oppose rotation of the first insulator relative to the cap plate, the first connection portion being eccentric with respect to a central line of the first terminal hole, and a second connection portion that mates the first insulator to the electrode terminal so as to oppose rotation of the electrode terminal relative to the first insulator.
Abstract:
A rechargeable battery includes an electrode assembly, a case housing the electrode assembly, an electrode terminal electrically connected to the electrode assembly and a cap plate sealing the case, the cap plate having an electrolyte injection opening. The electrolyte injection opening has a first opening having a first diameter and a second opening having a second diameter both defined by an inner wall of the cap plate, the second diameter being smaller than the first diameter, and a first guide portion between the first opening and the second opening. A sealing cap seals the electrolyte injection opening and includes a sealing member engaging the inner wall of the first opening and a fixing member coupled to the sealing member and engaging the inner wall of the second opening, wherein a portion of the fixing member is spaced from the inner wall of the second opening.
