A stable and high-capacity anode for lithium-ion battery: Fe2O3 wrapped by few layered graphene

Fe 2 O 3 wrapped by few layered graphene nanosheets composites (Fe 2 O 3 -FLG) have been synthesized via a facile and massive one-step P-milling method, which is effective in reducing the particle size of Fe 2 O 3 and exfoliating the graphite into FLG . The composite shows good electrochemical performance due to the tight wrapping of FLG nanosheets , which is beneficial to electric conductivity and integrity of the electrode. The sample treated under 20 h retains a reversible capacity of 758 mAh g −1 at 200 mA g −1 after 300 cycles, which equals to 88% of its theoretic capacity. With the superior electrochemical performance, Fe 2 O 3 -FLG composites prepared via the P-milling method could be promising as anode materials for high performance lithium-ion batteries.
