文摘

Using a green and effective method based on the solid state reaction between FePO₄路2H₂O and KBH₄, high pure Fe₂P nanoparticles are successfully prepared. The mass ratio of FePO₄路2H₂O to KBH₄ has a decisive influence on the composition of the products. Moreover, Fe₂P nanoparticles exhibit considerably high discharge capacities and excellent rate capability as the anode materials for nickel-based rechargeable batteries. The reversible discharge capacities are 413 and 343聽mAh聽g^鈭? at currents of 100 and 500聽mA聽g^鈭?, respectively. It is expected that Fe₂P nanoparticles have potential applications in nickel-based rechargeable batteries.
