Fabrication and characterization of Li0.5Fe2.5O4 octahedrons via a TEA-assisted route

Octahedral-like Li 0.5 Fe 2.5 O 4 crystallites have been fabricated using a TEA-assisted route under mild conditions. The as-prepared powders were characterized in detail by conventional techniques such as XRD, TEM, and FESEM. The saturation magnetization ( M s), remnant magnetization ( M r), and coercivity ( H c) have been determined to be 84, 6 emu/g, and 85 Oe, respectively. Meanwhile, the electrochemical properties of Li 0.5 Fe 2.5 O 4 demonstrate that it delivers a large discharge capacity, which might find possible application as an electrode material in lithium cells.
