| Abstract | alpha-Fe2O3 has been regarded as a promising candidate as anode materials for high energy-density lithium-ion batteries, because of its high capacity, low cost and environmental affinity. A facile hydrothermal route has been developed to synthesize monocrystalline microporous and mesoporous alpha-Fe2O3 particles by using anions Cl- and F- as pore-formation additives in precursor solution, respectively. Electrochemical investigation indicates that the mesoporous alpha-Fe2O3 particles display higher cyclic stabilities and capacity retentions than the microporous alpha-Fe2O3 particles at different current densities, although their sizes are in micrometer range, which indicate that the mesoporous alpha-Fe2O3 particles are promising anode candidate for high energy-density lithium-ion batteries. Furthermore, this facile hydrothermal route using anion Cl- or F- as pore-formation additives may be extended to synthesis of other porous metal oxides. (C) 2014 Elsevier B.V. All rights reserved. |
