    Abstract: PROBLEM TO BE SOLVED: To provide a welding method which scarcely cause a damage on a separator when welding a collector to an electrode body, and to provide a battery and a separator. SOLUTION: A laminate electrode body 100 laminating a positive electrode plate P and a negative electrode plate N with a separator S interposed therebetween is welded to collector plates 110, 120. A separator S having a sulfonation region V subjected to sulfonation, and a non-sulfonation region X not subjected to sulfonation is used. When the positive electrode collector plate 110 is welded to the laminate electrode body 100, the positive electrode collector plate 110 is welded in a state where the non-sulfonation region X is arranged in a place to which heat is transmitted easily.

    Abstract: A rechargeable battery exchanging method which exchanges rechargeable batteries of an assembled battery to rebuild new assembled battery. The method includes discharging a rechargeable battery derived from an assembled battery until the rechargeable battery becomes a fully discharged state and storing the rechargeable battery in a storage region for a predetermined period of time or longer from when the rechargeable battery becomes the fully discharged state to prepare a reusable rechargeable battery. The method further includes rebuilding a regenerated assembled battery by combining the stored reusable rechargeable battery with a stored reusable rechargeable battery derived from other assembled batteries or combining the stored reusable rechargeable battery with a fresh rechargeable battery.
