Document Type and Number:
Japanese Patent JP6629110
Kind Code:
B2
Abstract:
A nonaqueous electrolyte battery includes: a positive electrode containing a positive electrode active material made of a compound represented by a compositional formula of LiMn 1-x-y Fe x A y PO 4 (wherein A is at least one selected from the group consisting of Mg, Ca, Al, Ti, Zn and Zr, 0¤x¤0.3, and 0¤y¤0.1); a negative electrode containing a negative electrode active material made from a titanium composite oxide; and a nonaqueous electrolyte, wherein a ratio (I P-F /I P-O ) of a peak intensity (I P-F ) of a P-F bond to a peak intensity (I P-O ) of a P-O bond on the surface of the positive electrode, which are measured by X-ray photoelectron spectroscopic analysis, is 0.4 or more and 0.8 or less.
