Synergistic effect of hierarchical SnO2 nanorods/Fe2O3 hexahedrons with enhanced performance as lithium ion battery anodes
Source abstract
Abstract
Abstract Hierarchical SnO2-Fe2O3 nanocomposites composed of SnO2 nanorods and Fe2O3 hexahedrons are successfully prepared by a two-step hydrothermal method. The lithium ion batteries (LIBs) based on as-synthesized products are fabricated to investigate their electrochemical performance. As an anode material for LIBs, SnO2-Fe2O3 nanocomposites deliver a high capacity of 1022 mAh g−1 at 100 mA g−1 after 100 cycles. The cycling stability and rate performance of the nanocomposites are significantly improved. The enhanced performances benefit from the synergistic effect of SnO2 nanorods and Fe2O3 hexahedrons. The iron (Fe) nanoparticles reduced from Fe2O3 not only facilitate the conversion reaction of SnO2, resulting in the high capacity, but also increase the conductivity of the material. In addition, SnO2 serves as a matrix to protect Fe2O3 from agglomeration, and the hierarchical structure effectively buffers volume changes, thus enhancing the cycling life of LIBs.
