Abstract

La présente invention concerne la synthèse d'un nouveau matériau, le phosphite de titane (iii) [ti2(hpo3)3], 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.
