Abstract

Iron phosphate (Fe(II) ₂P ₂0 ₇) microspheres composed of self-assembled nanorods were prepared by means of thermal dehydrogenation followed by thermochemical reduction of hydrothermally- synthesized FePO ₄·2H ₂0 at 400°C under a H ₂ atmosphere. The phase and morphological evolutions of FePO ₄·2H ₂0 and Fe ₂P ₂O ₇ products were characterized by X-ray diffraction. The Fe ₂P ₂O ₇ electrode as a new anode showed higher specific capacities (490 mA h g ^-1 after 10 cycles at a rate of 100 mA g ^-1) and better cyclic performances than FePO ₄· 2H ₂0.
