BATTERY AND BATTERY MANUFACTURING METHOD, AND BATTERY CORE FABRICATION METHOD, CORE FABRICATION DEVICE, AND CORE

Provided are a method for manufacturing a cell that does not require a deformation process by pressing to provide a cell that is inexpensive and has high strength, and a method and apparatus for manufacturing a core. The method for manufacturing a cell includes: a first step of manufacturing a core 20 using a core manufacturing apparatus, the apparatus including a pair of winding shafts 5, 5 that are disposed with a rotation center of the apparatus interposed therebetween, the pair of winding shafts 5, 5 orbitally moving about the rotation center; and a second step of fabricating a laminated electrode member 25 with a sheet-shaped positive electrode 21, a sheet-shaped negative electrode 22 and a pair of sheet-shaped separators 23, 23 interposed thereto to be arranged alternately with the electrodes; and winding the laminated electrode member 25 around a circumferential surface of the core 20, wherein the first step includes: inserting a sheet S having a higher strength than the separators between the winding shafts 5, 5; orbitally moving the pair of winding shafts 5, 5; and then, adhesively bonding or melt-bonding overlapped portions of the sheet S at the winding shafts 5, 5.
