Secondary battery manufacturing method and a manufacturing apparatus

PROBLEM TO BE SOLVED: To provide a manufacturing method and manufacturing device of a secondary battery capable of coping with manufacture of a large-capacity lithium secondary battery and with improved productivity as compared with conventional manufacturing facilities. SOLUTION: Electrode plates made of a plurality of cathode plates and anode plates are arranged on a continuous separator used for partitioning of the electrode plates so as to retain a designated interval for each electrode plate and make a tab arranged on the electrode plates locate on the outside of the continuous separator; an other continuous separator used for partitioning of the electrode plates is overlapped on the continuous separator on which the electrode plates are arranged; both the continuous separators in the peripheries of the electrode plates are glued by pasting by heating fusion; and the cathode plates and the anode plates are stored in a laminated state so as to be alternately overlapped with each other via the continuous separators.
