    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.
