TREATING METHOD OF NON-AUQEOUS ELECTROLYTE AND METHOD OF FABRICATING BATTERY

A treating method of a nonaqueous-electrolyte and a method of fabricating a battery are provided. The treating method is suitable for being performed prior to injecting a nonaqueous-electrolyte into a containing region of the battery. The treating method includes performing at least one first voltage process or at least one second voltage process on the nonaqueous-electrolyte. The first voltage process includes as follows. A first voltage is applied to the nonaqueous-electrolyte. The voltage is adjusted gradually from the first voltage to a second voltage. The voltage is adjusted gradually from the second voltage to the first voltage. The second voltage process includes as follows. A third voltage is applied to the nonaqueous-electrolyte for a predetermined time.
