Abstract

La présente invention concerne la synthèse d'un nouveau matériau, le phosphite de titane (iii) [ti2(hp03h], qui n'existait pas auparavant dans la littérature. Ce composé cristallise dans un système hexagonal, groupe d'espace p63/m. Cette synthèse a été réalisée dans le cadre d'une application du stockage de l'énergie. Jusqu'à présent, dans les batteries, les phosphites n'ont été utilisés que sous formes organiques comme additifs dans les électrolytes jouant le rôle de stabilisateurs, permettant ainsi une meilleure sécurité d'utilisation. Dans la littérature, les phosphites inorganiques de métaux n'ont jamais été utilisés comme matériau d'anode dans les batteries rechargeables lithium-ion. Ceci fait l'objet de ce travail.The present invention relates to the synthesis of a new material, titanium phosphite (iii) [ti2 (hp03h), which did not previously exist in the literature.This compound crystallizes in a hexagonal system, space group p63 / m This synthesis was carried out in the context of an application of energy storage Until now, in batteries, phosphites have only been used in organic forms as additives in electrolytes acting as stabilizers. Thus, in the literature, inorganic metal phosphites have never been used as anode material in rechargeable lithium-ion batteries, which is the subject of this work.
