Document Type and Number:
Japanese Patent JP3733292
Kind Code:
B2
Abstract:
An electrode material for an anode of a rechargeable lithium battery contains a particulate comprising an amorphous M·A·X alloy with a substantially non-stoichiometric ratio composition,
wherein M indicates at least one element selected from a group consisting of Si and Ge,
A indicates at least one element selected from a group consisting of transition metal elements Cr, Mn, Fe, Co, Ni, Cu, Mo, Tc, Ru, Rh, Pd, Ag, Ir, Pt, Au, Ti, V, Y, Sc, Zr, Nb, Hf, Ta, and W, and
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%, and the amount of the elements O and F in said alloy does not exceed 5 % per weight each, at least 0.05 % weight of the elements 0 or F is present, and any O or F is predominantly located at the surface of said alloy particulate.
