<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a nonaqueous electrolyte secondary battery having an excellent charge/discharge characteristic and excellent in productivity. <P>SOLUTION: The nonaqueous electrolyte secondary battery is provided with a negative electrode containing a carbon material capable of storing and releasing lithium ions, a positive electrode and a nonaqueous electrolyte. When the nonaqueous electrolyte secondary battery is charged for the first time, current density between the positive electrode and the negative electrode is set to 3 mA/cm<SP>2</SP>or above until a predetermined period elapses from the start of charging, and set less than 3 mA/cm<SP>2</SP>after the predetermined period (a period until electric charge equivalent to an irreversible capacity portion of the negative electrode is charged at current density of 3 mA/cm<SP>2</SP>or above) elapses. <P>COPYRIGHT: (C)2004,JPO |
