Abstract
Disclosed is a method for manufacturing a cell which includes: a first step of manufacturing a core using a core manufacturing apparatus, the apparatus including a pair of winding shafts disposed with a rotation center of the apparatus interposed therebetween, the pair of winding shafts orbitally moving about the rotation center; and a second step of fabricating a laminated electrode member with a sheet-shaped positive electrode, a sheet-shaped negative electrode and a pair of sheet-shaped separators interposed thereto to be arranged alternately with the electrodes; and winding the laminated electrode member around a circumferential surface of the core. The first step includes: inserting a sheet having a higher strength than the separators between the winding shafts; orbitally moving the pair of winding shafts; and adhesively bonding or melt-bonding overlapped portions of the sheet at the winding shafts.
