Summary:PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery having high capacity and high overdischarge cycle characteristics and to provide the manufacturing method of the nonaqueous electrolyte secondary battery. SOLUTION: The nonaqueous electrolyte secondary battery includes a positive electrode 3 containing a positive electrode active material, a negative electrode 6 containing a negative electrode active material, and a nonaqueous electrolyte. A lithium-containing molybdenum oxide represented by a chemical formula: LixMoO2(0.05≤x≤0.25) in a full discharged state is used as the negative electrode active material. The lithium-containing molybdenum oxide can be obtained by allowing lithium to react with molybdenum dioxide electrochemically, for example. COPYRIGHT: (C)2008,JPO&INPIT
