Abstract
Official abstract text for this publication.
The present invention relates to an apparatus for sealing a secondary battery. The apparatus comprises: a sealing member thermally fusing and sealing a sealing surface of a pouch in which an electrode assembly is accommodated; and a cooling member cooling the sealing surface.
First claim
Opening claim text (preview).
The invention claimed is: 1. An apparatus for sealing a secondary battery, the apparatus comprising: a sealing member thermally fusing and sealing a sealing surface of a pouch in which an electrode assembly is accommodated; and a cooling member cooling the sealing surface, wherein the cooling member is configured to abut and conductively cool an inner end of the sealing surface, an outer end of the sealing surface, or both, to prevent an internal resin layer of the sealing surface from flowing to an accommodation part of the pouch and to an external direction of the sealing surface, wherein the cooling member is provided with an internal cooling part and an external cooling part, which respectively cool the inner end and the outer end of the sealing surface with the sealing member therebetween, and wherein the internal cooling part and the external cooling part have cooling temperatures different from each other. 2. The apparatus of claim 1 , wherein the sealing member thermally fuses and seals top and bottom surfaces of the sealing surface at the same time. 3. The apparatus of claim 1 , wherein the cooling member cools top and bottom surface of the sealing surface at the same time. 4. The apparatus of claim 1 , wherein the internal cooling part disposed on the inner end of the sealing surface has a cooling temperature higher than that of external cooling part. 5. The apparatus of claim 1 , wherein the cooling member and the sealing member are disposed without being closely attached to each other to secure an insulation and deformation space between the cooling member and the sealing member. 6. The apparatus of claim 1 , wherein an insulation material is provided between the cooling member and the sealing member. 7. An apparatus for sealing a secondary battery, the apparatus comprising: a sealing member thermally fusing and sealing a sealing surface of a pouch in which an electrode assembly is accommodated; and a cooling member cooling the sealing surface, wherein the cooling member is configured to abut and conductively cool an inner end of the sealing surface, an outer end of the sealing surface, or both, to prevent an internal resin layer of the sealing surface from flowing to an accommodation part of the pouch and to an external direction of the sealing surface, wherein the cooling member is provided with an internal cooling part and an external cooling part, which respectively cool the inner end and the outer end of the sealing surface with the sealing member therebetween, and wherein the internal cooling part and the external cooling part have cooling surfaces having contact areas having different sizes from each other, the contact areas being configured to contact the sealing surface of the pouch, wherein the internal cooling part and the external cooling part have cooling temperatures different from each other. 8. The apparatus of claim 7 , wherein the cooling surface of the internal cooling part disposed on the inner end of the sealing surface has a cooling contact area having a size that is greater than that of the external part.
