  • Patent number: 11916258
    Abstract: A secondary battery comprises an electrode assembly, a can, and an insulator. The electrode assembly includes a first electrode, a separator, and a second electrode alternately stacked and wound. The can has an accommodation part accommodating the electrode assembly therein, and the can comprises a first can and a second can having cylindrical shapes open in a direction facing each other. The insulator insulates an overlapping portion between the first can and the second can. The first can is electrically connected to the first electrode, and the second can is electrically connected to the second electrode. The insulator has a short-circuit induction through-part defined by a through-hole or a cutoff line, such that a short circuit occurs between the first can and the second can through the short-circuit induction through-part when it is deformed in shape as heat or a pressure is applied to contract or expand the insulator.

  • Patent number: 9865677
    Abstract: Provided is a super junction semiconductor device. The super junction semiconductor device includes a vertical pillar region located in an active region and horizontal pillar regions located in a termination region that are connected with each other while simultaneously not floating the entire pillar region in the termination region. Thus, a charge compensation difference, generated among pillar regions, is caused to be offset, although the length of the termination region is relatively short.
