Facile construction of clustered Fe2O3/TiO2 composite for improved lithium storage performance

Herein, to stabilize the lithium storage property of Fe2O3, a characteristically clustered composite composed of adjacent Fe2O3 and TiO2 secondary nanoparticles has been constructed by a well-designed proposal. It is suggested that the adjacent durable TiO2 nanoparticles can contribute to improve the structural stability of Fe2O3 nanoparticles by preventing the aggregation of Fe2O3 nanoparticles and restricting the pulverization of Fe2O3 nanoparticles. As a result, the as-prepared composite exhibits improved performance as a promising anode material for lithium-ion batteries, revealing high reversible capacity of 1234 mAh g(-1) after 320 cycles at 200 mA g(-1) as well as 792 mAh g(-1) after 600 cycles even at 1000 mA g(-1).
