Lithium titanate, Li4Ti5O12 (LTO) has drawn significant attention in the lithium ion battery because it shows some interesting features such as a low toxicity and low volume change (2-3%) on both lithium insertion and de-insertion, along with an excellent cycling life. Especially, the mesoporous LTO microspheres are considered as an ideal anode material because of their good rate performance, morphological properties, and a large tap density. However, it is very challenging to synthesize monodispersed LTO microspheres with desirable structural characteristics and electrochemical performances. In this study, LTO microspheres were synthesized using a facile process and cheap Ti-source (TiOSO4). The round shaped secondary particles (μm scale) were consisted of LTO primary particles (< 100 nm). The structural properties and electrochemical performances of Li4Ti5O12 microspheres will be discussed in the Meeting.
