Abstract
With the increasing demand for light, small, high power rechargeable lithium ion batteries in the appli-cation of mobile phones, laptop computers, electric vehicles, hybrid electric vehicles, electrochemical energy stor-age, and smart grids, the development of anode materials with high safety, environmental benignity, high power density, and long cycle life is in progress in recent years. The spinel lithium titanium oxide (Li4Ti5O12) anode has become more attractive as alternative anode because of its high safety, abundant titanium dioxide raw materials, stable charge/discharge voltage plateau of 1.5 V(vs.Li/Li+),and excellent cycling performance due to its zero-strain volume during charge/discharge process. However, the commercial use of Li4Ti5O12anode material has been hin-dered by the low intrinsic electronic conductivity. This review focuses on recent studies of the electronic structure and performance, synthesis methods and strategies for improvement in the lithium storage capacity, charge/discharge characteristics, then on its near future development.关键词
