<p>Disclosed are a method and a device for checking the insulation of a pouch type secondary battery capable of easily detecting whether or not the insulation of a pouch is destroyed for the pouch type secondary battery. The method for checking the insulation of the pouch type secondary battery according to the present invention is a method for checking a pouch type secondary battery having a pouch, as exterior materials, including an insulating layer, a metal layer, and an adhesive layer and comprises a step of bringing a first probe part in contact with the metal layer of the pouch; a step of bringing a second probe part into contact with an electrode of the pouch type secondary battery; a step of applying a voltage to both ends of the first probe part and the second probe part; and a step of detecting the separation of the metal layer and the adhesive layer of the pouch. [Reference numerals] (S110) Contact a first probe unit in pouch metal layer;(S120) Contact a second probe unit with an electrode;(S130) Apply electricity to both ends of the first and second probe units;(S140) Store secondary battery for predetermined time;(S150) Measure delamination of the metal layer and an adhesive layer</p> |
