METHOD OF MANUFACTURING DOPED ELECTRODE BODY

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing a doped electrode body to be assembled in a power storage device.SOLUTION: A method of manufacturing a doped electrode body 20' comprises: a first pinching step of pinching an electrode body 20 by a first holding jig 12; a second pinching step of pinching the first holding jig 12 by a second holding jig 13 having a lithium supply source 13b together with the electrode body 20; an infiltration step of infiltrating the electrode body 20 and the second holding jig 13 in a dope tank 11 filled with electrolytic solution 19; a dope step of connecting the electrode body 20 and the lithium supply source 13b through an external circuit 15 and doping lithium into an active material 22 to obtain a doped electrode body 20'; a take-out step of taking out at least the electrode body 20' from the dope tank 11; a second release step of releasing the first holding jig 12 from the second holding jig 13 having the lithium supply source 13b together with the electrode body 20'; and a first release step of releasing the electrode body 20' from the first holding jig 12.SELECTED DRAWING: Figure 1
