Lithium titanium oxide (Li4Ti5O12, LTO), a "zero-strain" anode material for Li-ion batteries (LIBs), exhibits excellent cycling performance. However, it shows poor conductivity, which is the major drawback and limits its applications. In a recent paper published in National Science Review, it is reported that static compression can highly improve the conductivity of LTO by pressure-induced amorphization and promoting ion migration defects for Li+. The results suggest amorphous LTO is a better anode material for LIBs.
