  • Secondary battery with enhanced connection of protection circuit unit to cap plate
    Patent number: 7968225
    Abstract: In the secondary battery, a lead plate is provided so as not to overlap the position of the sealing unit of the electrolyte injection hole to enhance the fixation of the lead plate to the upper surface of the cap plate of a cap assembly. The position of a connection terminal of a protective circuit unit corresponds to the position of the lead plate and together with the connection terminal shape the connection terminal is prevented from being exposed to the outside during hot-melt molding.
    Type: Grant
    Filed: September 23, 2010
    Date of Patent: June 28, 2011
    Assignee: Samsung SDI Co., Ltd.
    Inventors: Jeongdeok Byun, Kyungwon Seo, Nohyun Kwakg, Sangkwon Nam, Seok Koh, Bohyun Byun
