Porous electrode materials with both high rate capabilities and long cycle lives are significant to satisfy the urgent demand of energy storage. Furthermore, a one dimensional structure can facilitate Li+ diffusion and accommodate the volume expansion. Here, porous MnFe2O4 microrods have been successfully synthesized by a room temperature reaction and then moderate annealing in an Ar atmosphere. The porous MnFe2O4 electrodes exhibit high reversible capacity and outstanding cycling stability (after 1000 cycles still maitain about 630 mA h g-1 at the current density of 1 A g-1), as well as high coulombic efficiency (>98%). Moreover, even at a high current density of 4 A g-1, the porous MnFe2O4 microrods can still maintain a reversible capacity of 420 mA h g-1. These results demonstrate that the porous MnFe2O4 microrods are promising anode materials for high performance Li-ion batteries.
