Abstract 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.

轻松构建簇状 Fe2O3/TiO2 复合材料以提高锂存储性能

摘要 在此，为了稳定 Fe2O3 的储锂性能，通过精心设计的方案构建了由相邻的 Fe2O3 和 TiO2 二次纳米粒子组成的特征簇状复合材料。这表明相邻的耐用 TiO2 纳米粒子可以通过阻止 Fe2O3 纳米粒子的聚集和限制 Fe2O3 纳米粒子的粉化来提高 Fe2O3 纳米粒子的结构稳定性。因此，所制备的复合材料作为一种有前途的锂离子电池负极材料表现出更高的性能，在 200 mA g-1 和 792 mAh g-1 下循环 320 次后显示出 1234 mAh g-1 的高可逆容量即使在 1000 mA g-1 下也经过 600 次循环。
