<P>PROBLEM TO BE SOLVED: To provide a non-aqueous electrolyte secondary battery containing a lithium-contained complex oxide as a positive electrode active material which is improved in safety, more than a conventional one, at the time of internal short circuit without impairing high-rate characteristics. <P>SOLUTION: The non-aqueous electrolyte secondary battery is equipped with a positive electrode, a negative electrode, and a non-aqueous electrolyte, and the positive electrode contains active material particles capable of storing and releasing lithium ions, and the active material particles contain secondary particles. The secondary particles include coagulated primary particles, and the primary particles contain a lithium-contained complex oxide and has a metal oxide different from the lithium-contained complex oxide scattered between the primary particles. <P>COPYRIGHT: (C)2008,JPO&INPIT |
