Abstract

Abstract: Rock salt-type LiTiO₂ was prepared by treating TiO₂(anatase) powder with concentrated aqueous solution of LiOH at 110℃ under atmospheric pressure and characterized by means of TEM, XRD, XPS and TG/DTG. The results show that rock salttype LiTiO₂ prepared by this method is a nanosized nonstoichiometric compound. Its crystal form is stable at annealing temperature ≤500℃. In air ambience, the rock salt-type LiTiO₂ possesses stronger water absorption.

Key words: rock salt-type LiTiO2, XPS, LiOH, Li+ ion battery
