  • Publication number: 20170194606
    Abstract: Disclosed is a pouch-type secondary battery, which prevents a metal layer made of a lamination sheet from being exposed outwards, and a method for manufacturing the same. The pouch-type secondary battery includes a pouch-type battery case; an electrode assembly mounted in the battery case; electrode leads of a positive electrode and a negative electrode, configured to have one end connected to the electrode assembly and the other end protruding out of the battery case; and a sealing portion configured to bond an upper sheet and a lower sheet of the battery case, wherein a tape having a metal foil is bonded to increase a moisture penetration path toward a terminal of the sealing portion.

  • Patent number: 9653724
    Abstract: A secondary battery according to the present disclosure includes a cell assembly including a unit cell having at least one non-coated passage formed across an electrode plate, a temperature sensor including a temperature sensing unit located within the non-coated passage and a sensor lead extending from the temperature sensing unit, and a battery case to receive the cell assembly and which is sealed in a state that the sensor lead is drawn outside. According to the present disclosure, a temperature change of the secondary battery may be measured quickly and correctly, and thus, the secondary battery may be controlled more minutely in response to a temperature change, and gas generated in the battery case during charging and discharging of the secondary battery may be easily discharged to a surrounding area of the cell assembly, thereby preventing a battery efficiency reduction phenomenon.
