摘要:
A battery module according to the present invention includes rechargeable batteries (100) that include a first terminal (140) and a second terminal (130) which protrude outward, the first terminal (140) including at least one differentiation portion (141, 145) formed of an indentation (141) or a protruding portion (145) to differentiate the first terminal (140) from the second terminal (130), and connection members (160) that electrically connect the rechargeable batteries (100), fixed to the first and second terminals (140, 130) of adjacent rechargeable batteries (100), including verification portions (167, 162) which fit the differentiation portions (141, 145) so as to improve assemblability and minimize contact resistance.
摘要:
Disclosed is a rechargeable battery (100) including an electrode assembly (10) having a positive electrode (11), a negative electrode (12), and a separator (13) interposed between the positive and the negative electrodes (11, 12). A case (34) mounts the electrode assembly (10) therein. A cap plate (30) is fitted to the case (34). Terminals (21, 22) are electrically connected to the electrode assembly (10), and exposed to the outside of the case (34). The rechargeable battery (100) further includes current collecting plates (50) having first protrusions (52) inserted within the electrode assembly (10), and second protrusions (54) welded to the lateral ends of the electrode assembly (10).
摘要:
A rechargeable battery adapted to prevent or reduce overcharge. A rechargeable battery includes a case containing an electrode assembly; a cap plate coupled to the case and sealing an opening of the case; a first electrode terminal connected to a first electrode of the electrode assembly and electrically connected to the case; a second electrode terminal connected to a second electrode of the electrode assembly and electrically insulated from the case when a pressure inside the case is less than a threshold pressure; and a short-circuit unit including a short-circuit member connected to the second electrode terminal, the short-circuit unit adapted to short-circuit the second electrode terminal to the case by swelling a portion of the case to contact the short-circuit member when the pressure inside the case is equal to or greater than the threshold pressure.
