Abstract

The electrochemical lithiation of FePO₄ particles is investigated by in situ high-resolution transmission electron microscopy (HRTEM), and the anisotropic lithiation mechanism is directly observed. For the first time and in contrast to the previous post mortem HRTEM observations, a sharp (010) phase boundary between LiFePO₄ and FePO₄ is observed, which migrates along the [010] direction during lithiation.
