Highly ordered staging structural interface between LiFePO4 and FePO4†
Abstract
A highly ordered interface between LiFePO4 phase and FePO4 phase with staging structure along the a axis and perpendicular to the b axis direction has been observed for the first time, in a partially chemically delithiated Li0.90Nb0.02FePO4 by advanced aberration-corrected annular-bright-field (ABF)
