Title:
MANUFACTURING METHOD FOR SECONDARY BATTERY AND MANUFACTURING METHOD FOR DOPED ELECTRODE
Document Type and Number:
WIPO Patent Application WO/2022/102381
Kind Code:
A1
Abstract:
The present invention is a manufacturing method for a secondary battery in which a doped electrode including an active material layer doped with an alkali metal is used. The doped electrode is manufactured by transporting an electrode, containing an active material layer, along a path passing through a doping tank containing a counter electrode unit and a doping solution containing ions of the alkali metal and an aprotonic organic solvent. The secondary battery is manufactured by causing the doped electrode that has come out from the doping tank to be dried so as to contain 5 parts by mass to 40 parts by mass of a component of the doping solution with respect to 100 parts by mass of the active material layer, and then using the dried doped electrode.
