摘要： PROBLEM TO BE SOLVED: To solve the problem that in a lithium secondary battery, when metal foreign matter such as iron is mixed, the metal foreign matter in the positive electrode elutes when the battery is charged and that is precipitated on a negative electrode through a separator and when a conductive path of metal is formed in the separator, a minute short circuit is generated between the positive electrode and the negative electrode and voltage failure of the battery is brought about.
SOLUTION: This is a manufacturing method of a non-aqueous electrolyte secondary battery in which at the time of first-time charging, 0.01%-0.1% of the battery capacity is charged and a shelf standing time of at least one hour or more and 48 hours or less is provided. Even if the metal foreign matter such as iron is mixed in the positive electrode plate, minute short circuit between the positive electrode plate and the negative electrode plate through a separator can be prevented and voltage failure of the battery can be greatly reduced.
