Hierarchically structured lithium titanate for ultrafast charging in long-life high capacity batteries.

High-performance Li-ion batteries require materials with well-designed and controlled structures on nanometre and micrometre scales. Electrochemical properties can be enhanced by reducing crystallite size and by manipulating structure and morphology. Here we show a method for preparing hierarchically structured LiTiO yielding nano- and microstructure well-suited for use in lithium-ion batteries.
