英文摘要Iron hydroxyl-phosphate with a uniform spherical particle size of around 1 mu m, a compound of the type Fe(2-y)square(y)(PO(4))(OH)(3-3y)(H(2)O)(3y-2) (where square represents a vacancy), has been synthesized by hydrothermal methods. The particles are composed of spheres of diameter <100 nm. The compound exhibits good electrochemical performance, with reversible capacities of around 150 mAh g(-1) and 120 mAh g(-1) at current densities of 170 mAg(-1) and 680 mAg(-1), respectively. The stability of crystal structure of this material was studied by TGA and XRD which show that the material remains stable at least up to the temperature 200 degrees C. Investigation of the electronic structure of the iron hydroxyl-phosphate by GGA+U calculation has indicated that it has a better electronic conductivity than LiFePO(4).
