Abstract:
We synthesized a core-shell structure with graphene as the shell and nano-hollow γ-Fe2O3 as the core through a Kirkendall process at room temperature. When this hybrid is used as an anode material for lithium-ion batteries, it exhibits a remarkable electrochemical performance: a high reversible capacity of 1095, 833, and 551 mA h g(-1) at the current rates of 0.1 C, 1 C, and 2 C, respectively. When evaluated at 10 C, the capacity can still reach 504 mA h g(-1).
