Minimizing the particle size and constructing specific structures to accommodate the volumetric change of anodes for secondary batteries are significant. Herein, we develop a spiral [email protected] nanowire, which reduces the agglomeration of nanoparticles (approximate to 10 nm) and accommodates the volumetric change of Fe2O3 during charge and discharge. The [email protected] nanowires remains a capacity of 770 mAh g(-1) after 550 cycles at 0.1C, which is higher than the [email protected] nanospheres without a spiral morphology. A stable rate-performance even after testing repeatedly three rounds is also obtained. (c) 2020 Elsevier B.V. All rights reserved.
