<P>PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery with rise of inner resistance restrained due to repetition of charge and discharge. <P>SOLUTION: The nonaqueous electrolyte secondary battery 1 includes a cathode containing a cathode active material, an anode containing an anode active material and nonaqueous electrolyte. As the cathode active material, a compound expressed in a general formula: Li<SB>v</SB>M1<SB>w</SB>PO<SB>4</SB>(provided, 0≤v≤2, 0.8≤w≤1.2, and M1 is 3d transition metal) is used, and the nonaqueous electrolyte contains 3.0% by mass or less of vinylene carbonate and 4.0% by mass or less of organic silicide with an Si-N bond to a total mass of the nonaqueous electrolyte. <P>COPYRIGHT: (C)2010,JPO&INPIT |
