<P>PROBLEM TO BE SOLVED: To provide a non-aqueous electrolytic solution secondary battery which has excellent reliability with less internal short-circuit by easily removing conductive foreign matters mixed into a positive electrode. <P>SOLUTION: In a manufacturing method of the non-aqueous electrolytic solution secondary battery, an active material in a non-charged state and the active material in a chargeed state are contained in the positive electrode in an electrode plate group before contacted with an electrolytic solution. In the manufacturing method of a second invention, an additive reduced on a negative electrode at a potential of 1.5 V vs. Li/Li<SP>+</SP>or more is mixed into the electrolytic solution, and only the positive electrode is charged at a first-time charging. Furthermore, in the manufacturing method of a third invention, a compound reduced at the potential of 1.5 V vs. Li/Li<SP>+</SP>or more is mixed into the negative electrode, and only the positive electrode is charged at a first-time charging. <P>COPYRIGHT: (C)2007,JPO&INPIT |
