Erythrocyte‐Like Single Crystal α‐Fe2O3 Anode Synthesized by Facile One‐Step Hydrothermal Method for Lithium‐Ion Battery

Abstract Transition metal oxides Fe2O3 as lithium‐ion battery anode has aroused intense interest as a result of its high capacity (1007 mA h g−1). Nevertheless, the significant volume expansion during the cycling procession causes its capacity to decay sharply as the anode of lithium‐ion battery. Th...

Description
Summary:Abstract Transition metal oxides Fe2O3 as lithium‐ion battery anode has aroused intense interest as a result of its high capacity (1007 mA h g−1). Nevertheless, the significant volume expansion during the cycling procession causes its capacity to decay sharply as the anode of lithium‐ion battery. The size and morphology of materials are important factors improving the stability of electrode materials. However, most of the excellent morphology design needs complex processes. The single‐crystalline erythrocyte‐like α‐Fe2O3 nanoparticles are synthesized by one‐step hydrothermal method to improve the electrochemical properties of the α‐Fe2O3 anode, and the Li+ storage kinetics of the erythrocyte‐like α‐Fe2O3 anode are investigated. As a lithium‐ion battery anode material, the erythrocyte‐like α‐Fe2O3 anode exhibits an eminent reversible capacity of 1200.2 mA h g−1 at 0.1 C after 100 cycles. In comparison to raw α‐Fe2O3, the erythrocyte‐like α‐Fe2O3 performs with a better rate property. The special morphological design can effectively improve the stability of α‐Fe2O3 electrode materials.
