Abstract: The time to manufacture laminated batteries is shortened. A cutting process includes folding or winding a binding margin continuously with a separating portion of a separator member and cutting the separator member with a cutter to form the binding margin. A transfer process includes transferring a laminate body and the binding margin. A main portion has a length at least twice a width of a wider side surface of the laminate body. A laminate body formation process is at least partially performed in parallel with a binding process.

Abstract: A power storage cell comprises a cell case and a wound electrode assembly. The wound electrode assembly includes a first electrode, a separator, a second electrode, and a fixing member. In a winding direction of the wound electrode assembly, the first electrode has a first end portion. The second electrode has a second end portion. The separator has a third end portion. In the winding direction, the second end portion is positioned within a region spanning from the first end portion to the third end portion. The first end portion consists of the first foil. The second end portion consists of the second foil. The fixing member fixes the wound electrode assembly at the third end portion. The expression “0.9×T2≤Tf≤1.1×(T1+T2)” is satisfied. T1 represents a thickness of the first foil. T2 represents a thickness of the second foil. Tf represents a maximum thickness of the fixing member.
