摘要：NOVELTY - A controllable lithium titanate/titanium dioxide nano composite particle comprises lithium titanate which is lithium-titanium-oxide in a precursor. The titanium dioxide is a mixed phase composed of an anatase phase and rutile phase. The controllable lithium titanate/titanium dioxide nano composite particle has particle diameter of 10-40 nm and chain-shaped structure. USE - Controllable lithium titanate/titanium dioxide nano composite particle for use as cathode material of lithium ion battery (all claimed). ADVANTAGE - The controllable lithium titanate/titanium dioxide nano composite particle has excellent rate performance, improved specific capacity, additional lithium storage space, high-rate performance, and high electrochemical activity. DETAILED DESCRIPTION - A controllable lithium titanate/titanium dioxide nano composite particle comprises lithium titanate which is lithium-titanium-oxide of formula: Li4Ti5O12 and lithium-titanium-oxide of formula: Li2TiO3 in a precursor. The titanium dioxide is a mixed phase composed of an anatase phase and rutile phase. The controllable lithium titanate/titanium dioxide nano composite particle has particle diameter of 10-40 nm and chain-shaped structure. INDEPENDENT CLAIMS are included for the following: (1) preparation method of controllable lithium titanate/titanium dioxide nano composite particle; and (2) use of controllable lithium titanate/titanium dioxide nano composite particle as cathode material for lithium ion battery.
