Abstract

The present invention is to provide a package containing a roll of a long electrode plate which is a package for storing a roll of a long electrode plate, wherein it is possible to simplify the work process of containing and packaging the roll of a long electrode plate and prevent the electrode performance from deterioration without the electrode plate to absorb moisture, be damaged or the like, and the collection of packaging material constituting the package is not necessary since the packaging material is disposable after opening of the package. A cushioning having a hole and a flange having a hole are respectively arranged in this order on both side surfaces of a roll of a long electrode plate comprising a long electrode plate, which is wound to a core, or of a group of rolls of a long electrode plate comprising two or more rolls of a long electrode plate, so as to align the core hole, the cushioning hole and the flange hole; the roll of a long electrode plate, the cushioning and a core cap are assembled by fitting a cylindrical portion of the core cap from the flange hole side, the core cap comprising the cylindrical portion, which fits into each hole, and a collar portion; and further the roll of a long electrode plate is packed to seal with at least dry gas and/or desiccating agent so that the pair of flanges is grounded to suspend and support the roll of a long electrode plate by making both configurations of the pair of flanges larger than that of the roll of a long electrode plate in order to prevent the roll of a long electrode plate from being grounded.

Claims

1. A package containing a roll of a long electrode plate, wherein a cushioning having a hole and a flange having a hole are respectively arranged in this order on both side surfaces of a roll of a long electrode plate comprising a core having a hole and a long electrode plate, which is wound to the core, or on both side surfaces of a group of rolls of a long electrode plate comprising two or more rolls of a long electrode plate and one or more cushionings disposed alternatively so that the side surfaces of the rolls of a long electrode plate are located next to each other disposing the cushioning having a hole therebetween, so as to align the core hole, the cushioning hole and the flange hole;

the roll of a long electrode plate, the cushioning and a core cap are assembled by fitting a cylindrical portion of the core cap from the flange hole side, the core cap comprising the cylindrical portion, which fits into each hole, and a collar portion; and

further the roll of a long electrode plate is packed to seal with at least dry gas and/or desiccating agent so that the pair of flanges is grounded to suspend and support the roll of a long electrode plate by making both configurations of the pair of flanges larger than that of the roll of a long electrode plate in order to prevent the roll of a long electrode plate from being grounded.

2. A package containing a roll of a long electrode plate according to claim 1, wherein an assemblage in which the cushioning and the flange are respectively assembled on both side surfaces of the roll of a long electrode plate or the group of rolls of a long electrode plate is packed in a pouch.

3. A package containing a roll of a long electrode plate according to claim 1, wherein at least dry gas is fed to a pouch in which a roll of a long electrode plate is packed and sealed.
