| 摘要 |
The present invention relates to a nonaqueous electrolyte secondary battery comprising an anode capable of doping with and dedoping from lithium: a cathode and a nonaqueous electrolyte. The anode includes a carbon material, a polymer material and an Sn-containing compound expressed by a below general formula (1). SnM<1>xM<2>yM<3>z (1) (In the formula, M<1 >designates at least one kind of material selected from (Co and Cu, and M<2 >designates at least one kind of material selected from Cr, Fe, Mn, Nb, Mo, W, B and P. M<3 >designates at least one kind of material selected from In, Ag, Zn and Al. x, y, and z are respectively represented by 0.1<x<=2, 0<y<=2 and 0<z<=1.)
