| 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) <?in-line-formulae description="In-line Formulae" end="lead"?>SnM<SUP>1</SUP><SUB>x</SUB>M<SUP>2</SUP><SUB>y</SUB>M<SUP>3</SUP><SUB>z</SUB> (1)<?in-line-formulae description="In-line Formulae" end="tail"?> (In the formula, M<SUP>1 </SUP>designates at least one kind of material selected from Co and Cu, and M<SUP>2 </SUP>designates at least one kind of material selected from Cr, Fe, Mn, Nb, Mo, W, B and P. M<SUP>3 </SUP>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.). |
