An electrode material for an anode of a rechargeable lithium battery, containing a particulate comprising an amorphous M.A.X alloy with a substantially non-stoichiometric ratio composition. ÄFor said formula M.A.X, M indicates at least one kind of an element selected from a group consisting of Si, Ge, and Mg, 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, Ba, Sr, Ca, La, Ce, C, P, S, Se, Te, B, Bi, Sb, Al, In, and Zn, where the element X is not always necessary to be contained. The content of the constituent element M of the amorphous M.A.X alloy is M/(M + A + X) = 20 to 80 atomic%.Ü 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. <IMAGE> |
