Abstract
A gas collecting apparatus for collecting gas generated in a secondary battery comprising an electrode assembly and a flexible pouch case containing the electrode assembly therein, the gas-collecting apparatus comprising an insert plate part including a through-hole and a pressing jig part having a gas moving path, and the gas-collecting apparatus capable of easily collecting the gas regardless of the standard size and shape of the secondary battery.
Claims10
A gas-collecting apparatus for collecting gas generated in a secondary battery comprising an electrode assembly and a flexible pouch case accommodating the electrode assembly therein,
- wherein the pouch case includes a first sheet covering one surface of the electrode assembly and a second sheet covering the other surface of the electrode assembly,
- wherein the gas-collecting apparatus comprises:
- an insert plate part in close contact with the first sheet inside the pouch case;
- and
- a pressing jig part in close contact with the insert plate part outside the pouch case with the first sheet interposed therebetween,
- wherein the insert plate part includes a through hole penetrating the insert plate part so that a first surface of the insert plate part facing the first sheet and a second surface opposite to the first surface are connected to each other, and
- wherein a gas moving path of which one end is connected to the through hole and through which the gas generated in the secondary battery flows is formed inside the pressing jig part.
