Abstract
A method of newly producing a lithium-ion secondary battery using an electrode plate of a used lithium-ion secondary battery includes providing the electrode plate of the used lithium-ion secondary battery; cleansing the electrode plate by polar solvent; and drying the electrode plate thereafter to obtain a cleansed electrode plate. The method includes forming an electrode body and attaching the cleansed electrode plate to the electrode body; and securing the electrode body inside a battery case. The method includes injecting non-aqueous electrolytic solution between the battery case and the cleansed electrode plate. The non-aqueous electrolytic solution includes lithium salt containing element fluorine and a pH level of which is in a range of 6 to 8. The method includes contacting the non-aqueous electrolytic solution with a basic lithium compound to form a pH-level-adjusted non-aqueous electrolytic solution. The method includes injecting the pH-level-adjusted non-aqueous electrolytic solution in the battery case.
