Self-stacked CuFe2O4-Fe2O3 porous nanosheets were prepared via a facile polyol-mediated route followed by calcination. Benefited from its highly porous structures and good electrical and ion conductivity of the well-dispersed CuFe2O4 phase in the matrix, the hybrid material exhibits high specific capacity of 910 mA h g-1 at 0.5 C after 200 cycles, superior capacity retention (0.02 % capacity loss per cycle) and good rate capability (417 mA h g-1 at 4 C) as a promising anode material for Li-ion batteries.
