Title (EN) ALLOY COMPOSITIONS FOR LITHIUM ION BATTERIES
(FR) COMPOSITIONS D'ALLIAGE POUR BATTERIES LITHIUM-ION
Abstract: front page image
(EN)Alloy compositions, lithium ion batteries, and methods of making lithium ion batteries are described. The lithium ion batteries have anodes that contain an alloy composition that includes a) silicon, b) aluminum, c) transition metal, d) tin, and e) a fifth element that contains yttrium, a lanthanide element, an actinide element, or a combination thereof. The alloy composition is a mixture of an amorphous phase that includes silicon and a nanocrystalline phase that includes an intermetallic compound of tin and the fifth element.
(FR)L'invention concerne des compositions d'alliage, des batteries lithium-ion et des procédés de fabrication de batteries lithium-ion. Les batteries lithium-ion comprennent des anodes contenant une composition d'alliage renfermant (a) du silicium, (b) de l'aluminium, (c) un métal de transition, (d) de l'étain, et (e) un cinquième élément contenant de l'yttrium, un élément lanthanide, un élément actinide ou une combinaison de ceux-ci. La composition d'alliage est un mélange d'une phase amorphe comprenant du silicium et d'une phase nanocristalline comprenant un composé intermétallique d'étain et du cinquième élément.
