文摘

We report a facile approach to synthesize nano-Li₄Ti₅O₁₂ anode material by a biphasic interfacial reaction route at the cyclohexane/water interface and a subsequent calcination process. The resultant materials were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, N2 adsorption/desorption, and electrochemical experiment. As an anode material for lithium-ion batteries, the resultant nano-Li₄Ti₅O₁₂ displays excellent rate capability and cycling stability, its specific capacity can remain at 150 and 126.6 mAh g⁻¹ after 50 cycles at 10 and 20 C, indicating its potential application for high-power lithium ion batteries.
