Sponge-like porous Ni1.8Fe1.2O4 nanocubes were prepared by heating Prussian blue analogue KNi (x) Fe3-x (CN)(6)center dot nH(2)O nanocubes. It is showed that the nanocubes exhibit nanoscale particles, multiple through-hole frameworks and high surface area owing to the emission organic molecules, such as CO (x) and NO (y) , during the heat treatment process in air at 300 A degrees C. When it is used as lithium-ion batteries (LIBs) anode material shows an outstanding rate performance with advanced capacities of 1268, 1189, 1156, 1052, 1028 and 858 mAh g(-1) at 100, 200, 500, 1000, 2000 and 5000 mA g(-1), respectively. The sponge-like porous and large specific surface area of nanocubes shorten the diffusion path for Li ion and electron and evidently mitigation bulk effects during discharge/charge process, which effectively improve electrochemical performance of LIBs. These results show that the sponge-like porous Ni1.8Fe1.2O4 nanocubes have a great application value as LIBs anode in view of its facile and effective preparation technology and excellent electrochemical performance.
