•Effect of CTAB on the morphology and crystallization of MnFe2O4.•The lowest coercivity of MnFe2O4 polyhedron is 11.9 Oe.•MnFe2O4 as anode for LIB shows good reversible capacity and cycle performances.
The uniform different morphologies MnFe2O4, including cube, truncated cube, polyhedron and octahedron, were successfully synthesized via a solvothermal route using cetyltrimethylammonium bromide. The results of control experiments revealed that the concentration of cetyltrimethylammonium bromide was an important factor, which affected the morphology and crystallization of MnFe2O4 submicro-crystals. All the prepared samples exhibited soft-magnetic behavior at room temperature. Especially, the coercivity of MnFe2O4 polyhedron with 200 nm diameter was 11.9 Oe, which was among the lowest values reported so far. Moreover, MnFe2O4 submicro-crystals with special morphologies demonstrated higher reversible capacity (about 1000 mAh g−1) and different cycle performances. After 50 cycles, polyhedron structure remained 428 mAh/g. The MnFe2O4 would have a potential application as anode material for lithium ion batteries.
