Abstract
Hematite (α-Fe2O3) multi-shelled hollow spheres (MSHSs) have been prepared by a facile spray drying method using iron(iii) citrate and sucrose as the precursors. The sucrose/iron(iii) citrate ratio plays an important role in the morphology of the products. Well-defined MSHSs can be obtained in a wide sucrose/iron(iii) citrate ratio of 0.25-1.5. The application of α-Fe2O3 MSHSs in lithium storage has been demonstrated. When used as the anode material for lithium-ion batteries, the α-Fe2O3 MSHSs exhibit a high reversible capacity of 979 mA h g-1, maintaining 861 mA h g-1 after 50 cycles.
