Novel Synthesis Method and Electrochemical Characteristics of Lithium Titanium Oxide as Anode Material for High Power Device

Lithium titanium oxide as anode material for energy storage prepared by novel synthesis method. Li₄Ti₅O₁₂ based spinel-framework structures are of great interest material for lithium-ion batteries. We describe here Li₄Ti₅O₁₂ a zero-strain insertion material was prepared by novel sol-gel method and by high energy ball milling (HEBM) of precursor to from nanocrystalline phases. According to the X-ray diffraction and scanning electron microscopy analysis, uniformly distributed Li₄Ti₅O₁₂ particles with grain sizes of 100 nm were synthesized. Lithium cells, consisting of Li₄Ti₅O₁₂ anode and lithium cathode showed the 173 mAh/g in the range of 1.0~3.0 V. Furthermore, the crystalline structure of Li₄Ti₅O ₁₂ didn't transform during the lithium intercalation and deintercalation process
