PRE-DOPING METHOD OF NONAQUEOUS SECONDARY BATTERY AND BATTERY OBTAINED BY PRE-DOPING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a pre-doping method of the alkali metal ions of a nonaqueous secondary battery which allows for easy handling of an electrode, without pasting a lithium metal or manufacturing a half-cell, and to provide a nonaqueous secondary battery using this method.SOLUTION: In a pre-doping method of a nonaqueous secondary battery having a positive electrode 1 and a negative electrode 2, an electrode 4 for compensation having an alkali metal ion source arranged not in contact with the positive electrode and negative electrode is arranged so as to be immersed in a pre-dope solution 5 where the alkali metal ions are eluted. A DC power supply 8 is connected between any one of the positive or negative battery electrode and the electrode for compensation, so that the direction of an electric field by the DC power supply is identical to the direction of the electrode plane of the battery electrode.
