ABSTRACT:
An electrode material for an anode of a rechargeable lithium battery, containing a particulate comprising an amorphous Sn.A.X alloy with a substantially non-stoichiometric ratio composition. For said formula Sn.A.X, A indicates at least one kind of an element selected from a group consisting of transition metal elements, X indicates at least one kind of an element selected from a group consisting of O, F, N, Mg, Ba, Sr, Ca, La, Ce, Si, Ge, C, P, B, Pb, Bi, Sb, Al, Ga, In, Tl, Zn, Be, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, As, Se, Te, Li and S, where the element X is not always necessary to be contained. The content of the constituent element Sn of the amorphous Sn.A.X alloy is Sn/(Sn+A+X)=20 to 80 atomic %. An electrode structural body for a rechargeable lithium battery, comprising said electrode material for an anode and a collector comprising a material incapable of being alloyed with lithium in electrochemical reaction, and a rechargeable lithium battery having an anode comprising said electrode structural body.
