摘要

An electrode material for a negative pole of a lithium secondary battery containing particles which comprises an amorphous Sn.A.X alloy having a substantially non-stoichiometric composition, wherein A represents at least one element selected from the transition metal elements, X is an optional component and represents at least one element selected from the group consiting of O, F, N, Mg, Ba, Sr, Ca, La, Ce, Si, Ge, C, P, B, Bi, Sb, Al, In, and Zn, and the content of the component Sn ¢Sn/(Sn+A+X)! is 20 to 80 atomic %. An electrode structure for a lithium secondary cell composed of the aforementioned electrode material for a negative electrode and a collector comprising a material which forms no alloy with lithium in an electrochemical reaction, and a lithium secondary cel having a negative pole comprising the electrode structure.
