An electrode material for an anode of a rechargeable lithium battery, containing a particulate comprising an amorphous Sn.cndot.A.cndot.X alloy with a substantially non-stoichiometric ratio composition. (For said formula Sn.cndot.A.cndot.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, Bi, Sb, Al, In, and Zn, where the element X is not always necessary to be contained. The content of the constituent element Sn of the amorphous Sn.cndot.A.cndot.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.

Cette invention se rapporte à un matériau électrode pour le pôle négatif d'une batterie secondaire au lithium, contenant des particules qui renferment un alliage Sn-A-X amorphe ayant une composition essentiellement non stoechiométrique, où A représente au moins un élément choisi parmi les éléments métalliques de transition, X est un composant optionnel et représente au moins un élément choisi dans le groupe constitué par O, F, N, Mg, Ba, Sr, Ca, La, Ce, Si, Ge, C, P, B, Bi, Sb, Al, In et Zn, et la teneur en composant Sn [Sn/(Sn+A+X)] est comprise entre 20 et 80 % atomique. Cette invention présente également une structure d'électrode pour une cellule secondaire au lithium composée par le matériau électrode mentionné ci-dessus pour une électrode négative et par un collecteur contenant un matériau ne formant pas d'alliage avec le lithium en réaction électrochimique, ainsi qu'une cellule secondaire au lithium ayant un pôle négatif comprenant cette structure d'électrode.
