Abstract
A polymer battery module (2) provided with tabs (4) is put in a package (5) and an open end part of the package (5) is heat-sealed by a heat-sealing machine (10). The heat-sealing machine (10) is provided with a pair of sealing heads (10a, 10b) respectively having sealing surfaces (12). The sealing surfaces (12) of the sealing heads (10a, 10b) are provided with recesses (11) in parts thereof corresponding to the tabs (4) of the polymer battery module (2) contained in the package (5) as located in place between the sealing heads (10a, 10b) for heat-sealing.
Claims26
A heat-sealing method comprising the steps of:
- putting a polymer battery module provided with a tab in a pouch package having one unsealed part through the unsealed part so that the tab is placed in the unsealed part of the pouch package;
- and
- heat-sealing the unsealed part of the pouch package with a pair of sealing heads respectively having sealing surfaces, at least one of which being provided with a recess in a part corresponding to the tab.
A heat-sealing method comprising the steps of:
- putting a polymer battery module provided with a tab in an embossed package;
- and
- heat-sealing the embossed package with a pair of sealing heads respectively having sealing surfaces, at least one of which being provided with a recess in a part corresponding to the tab.
A heat-sealing method comprising the steps of:
- putting a polymer battery module provided with a tab in a pouch package having at least one unsealed part so that the tab is placed in the unsealed part of the pouch package;
- and
- heat-sealing the unsealed part of the pouch package with a pair of sealing heads respectively having sealing surfaces, at least one of which being provided with a recess in a part corresponding to the tab, wherein the polymer battery module is provided with a pair of tabs, and the unsealed part of the pouch package is heat-sealed in a manner where adhesive films are interposed between the tabs and the unsealed part.
