Abstract

La présente invention concerne la synthèse d’un nouveau matériau, le phosphite de titane (+iii) et de lithium [liti(hpo3)2], qui n’existait pas auparavant dans la littérature. Ce composé présente un grand intérêt grâce à sa structure tridimensionnelle. Il cristallise dans un système quadratique de groupe d’espace i2d. Sa structure est construite à partir des octaèdres tio6, et des tétraèdres hpo3 qui partagent les sommets et forment des tunnels le long des trois axes cristallographiques a, b et c. Utilisé en tant que matériau d’électrode négative pour les batteries rechargeables, cette structure lui permet d’avoir une bonne tenue en cyclage, une résistance à la variation des régimes de cyclage et un comportement de puissance intéressant.
