NON-AQUEOUS ELECTROLYTE SECONDARY CELL

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 M M (1) (In the formula, Mdesignates at least one kind of material selected from Co and Cu, and Mdesignates at least one kind of material selected from Cr, Fe, Mn, Nb, Mo, W, B and P. Mdesignates 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.)
