ZnFe 2 O 4 /graphite composite was synthesized by a thermal decomposition method using expanded graphite as matrix. TheZnFe 2 O 4 nanoparticles with the size of 20–30 nm were embedded into the interlayers of graphite. The porous structureformed by the graphite sheets can not only alleviate the adverse eff ects caused by the volume change of the ZnFe 2 O 4 duringcycling, but also improve the lithium storage performance. The specifi c capacity of 1450 mAh g − 1 is achieved after150 charge/discharge cycles at 0.1 A g − 1 . Moreover, the composite still delivers the specifi c capacity of 229 mAh g − 1 atthe ultrahigh current density of 10 A g − 1 after 1800 cycles, showing outstanding electrochemical performance and excellentcycling stability. The composite has great potential for use in the high-power lithium-ion batteries.
