Abstract
A sealing apparatus may include a pair of sealing tool assemblies of an exothermic sealing tool, an endothermic sealing tool and an endothermic/exothermic device. The exothermic sealing tool and the endothermic sealing tool each may extends along a widthwise direction of a pouch, and may be juxtaposed with each other along a lengthwise direction of the pouch. The endothermic/exothermic device may be interposed between the exothermic sealing tool and the endothermic sealing tool to radiate heat to the exothermic sealing tool and absorbs heat from the endothermic sealing tool.
Claims18
A sealing apparatus for forming a first sealed portion by fusion provided at two lengthwise ends of a pouch of a pouch-type battery cell along a widthwise direction, the sealing apparatus comprising:
- a pair of sealing tool assemblies provided above and below the first sealed portion, respectively, each of the pair of sealing tool assemblies comprising:
- an exothermic sealing tool extending along the widthwise direction;
- an endothermic sealing tool extending along the widthwise direction and juxtaposed with the exothermic sealing tool along a lengthwise direction;
- and
- an endothermic/exothermic device interposed between the exothermic sealing tool and the endothermic sealing tool,
- wherein the endothermic/exothermic device simultaneously radiates heat to the exothermic sealing tool and absorbs heat from the endothermic sealing tool.
A sealing apparatus for forming a second sealed portion by fusion provided at one widthwise end of a pouch of a pouch-type battery cell along a lengthwise direction, the sealing apparatus comprising:
- a pair of sealing tool assemblies provided above and below the second sealed portion, respectively, each of the pair of sealing tool assemblies comprising:
- an exothermic sealing tool extending along the lengthwise direction;
- an endothermic sealing tool extending along the lengthwise direction and juxtaposed with the exothermic sealing tool along a widthwise direction;
- and
- an endothermic/exothermic device interposed between the exothermic sealing tool and the endothermic sealing tool,
- wherein the endothermic/exothermic device simultaneously radiates heat to the exothermic sealing tool and absorbs heat from the endothermic sealing tool.
