摘要：

Uniformly loaded alpha-Fe2O3/graphene nanocomposites are synthesized via hydrothermal routs. Enhanced lithium storage performance of lithium-ion battery anodes is realized from alpha-Fe2O3/graphene nanocomposites. Compared with pure alpha-Fe2O3 nanostructures, alpha-Fe2O3/graphene nanocomposites exhibit higher reversible capacity and better cycling performance. Their reversible capacity is up to 771 mA h g(-1) at C/10 rate, and maintains 73% after 30 cycles. Such behaviors can be attributed to high electron and Li-ion conductivity, large surface area, good mechanical flexibility of graphene nanosheets and the synergetic effect of graphene and alpha-Fe2O3 nanostructures. Our results indicate that alpha-Fe2O3/graphene nanocomposites are good candidates for high performance lithium-ion battery anodes. (C) 2011 Elsevier Masson SAS. All rights reserved.
