Figure 1. (A) Structure of the olivine-like LFMP. The Fe(Mn)O₆ octahedra are dashed with grey color for clarity and form layers in the ac plane. Adjacent layers are linked by PO₄ units, leaving some place for one-dimensional arrays of Li atoms along the b-axis (P is in blue, oxygen in red, and Li in green)^[26]. Copyright © 2008 Elsevier B.V. (B) Curved migration pathway calculated for lithium ion transport along the b-axis in LiFe_0.5Mn_0.5PO_4. The black spheres represent lithium ions, whereas the gray lines signify their migration trajectories^[11].
