Abstract: MnFe2O4 with one dimensional porous rod structure was synthesized based on microemulsion method and calcination with ferrous sulfate and manganese acetate as raw materials, bis (2-ethylhexyl) sulfosuccinate sodium salt as surfactant. The prepared MnFe2O4 rods show a diameter of about 200 nm and length of 2~3 μm with abundant mesopores of 13~35 nm. When tested as anode material of lithium ion batteries, the prepared MnFe2O4 exhibited a capacity over 630 mA·h·g-1 after 200 cycles at a current density 100 mA·g-1. It also shows good rate capability. The research shows that the MnFe2O4 with porous rod structure could be a good candidate for anode materials of lithium ion batteries.
