並列タイトル等Synthesis and Electrochemical Properties of Ramsdellite Type Lithium Titanate Anode Materials by Spray Pyrolysis
タイトル(掲載誌)Journal of the Japan Society of Powder and Powder Metallurgy
一般注記Ramsdellite type lithium titanate (Li2Ti3O7) powders were prepared by spray pyrolysis. Chemical and physical properties of Li2Ti3O7 powders were characterized by SEM, DTG, XRD and ICP. As-prepared Li2Ti3O7 precursor powders had a spherical morphology with hollow microstructure, but the irregular shaped morphology was obtained after the calcination above 900℃. The crystal phase of ramsdellite Li2Ti3O7 was obtained by the calcination at 1100℃. The first rechargeable capacities of Li2Ti3O7 anode were 168 mAh/g and 82 mAh/g at 0.1 mA/cm2 and 20 mA/cm2, respectively. The retention ratio of discharge capacity was 99% at 1 mA/cm2 after 100th cycle. The cycle performance of Li2Ti3O7 anode had also high stability at 50℃.
