Abstract:
1. A package containing a roll of a long electrode plate, wherein a pair of sheet cushionings having a hole and a pair of sheet flanges 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; wherein an assemblage in which the roll of a long electrode plate, the cushionings, the flanges and a pair of core caps are assembled by fitting a cylindrical portion of the core caps from the flange hole side is contained in a 20 to 500 μm thick pouch with dry gas or a desiccating agent, the core cap comprising the cylindrical portion, which fits into each hole, and a collar portion; wherein the pair of flanges are 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; wherein a taper form or a partial protruding form is applied to an outer circumferential surface of the cylindrical portion of the core cap; and wherein the flange has a structure disposing plural ribs between a pair of thin plates made of thermoplastic resin, wherein ribs are formed on the outer circumferential surface of the cylindrical portion of the core cap in parallel with a center axis of the core cap, whch are about 0.05 mm to 1 mm in height, and ring-form ribs are formed surrounding the outer circumferential surface of the cylindrical portion, which are lower in the height than the parallel ribs.
