Abstract

The full static picture of Li storage in Li ₄Ti ₅O ₁₂ is derived using the latest spherical aberration-corrected scanning transmission electron microscopy and first-principles calculations. The accommodation of the additional Li ⁺ is directly visualized and the distribution of electrons introduced by lithium insertion deduced. Moreover, Li ₄Ti ₅O ₁₂ is found to transform into Li ₇Ti ₅O ₁₂ on lithiation by developing a dislocation-free coherent hetero-interface.
