Three-dimensional　porous　Cu/Cu2O,　CuO,　CuO/NiO　were　prepared　on　Ni　foam　by　a　simple　two　step　method　which　consist　of　a　replacement　reaction　and　subsequent　thermal　treatment　method　at　various　temperature.　The　morphology　and　microstructure　of　the　samples　were　characterized　by　means　of　X-ray　diffraction　(XRD),　scanning　electron　microscopy　(SEM)　and　transmission　electron　microscopy　(TEM).　The　electrochemical　properties　of　the　samples　were　evaluated　by　galvanostatic　discharge-charge　cycling,　cyclic　voltammetry　and　impedance　spectral　measurements　on　cells　with　lithium　discs　as　counter　electrode　and　reference　electrode.　Compared　to　Cu/Cu2O　and　CuO/NiO,　the　sample　of　CuO　obtained　at　400　degrees　C　exhibited　the　best　electrochemical　performance　which　delivered　a　reversible　capacity　of　605.3　mAh　g(-1)　(89.8%　of　the　theoretical　capacity)　after　50　cycles　at　the　current　density　of　100　mA　g(-1),　without　noticeable　capacity　fading.　The　excellent　electrochemical　performance　of　porous　CuO　can　be　attributed　to　the　three-dimensional　porous　structure,　which　cannot　only　provide　large　surface　area　but　also　facilitate　Li+　and　electron　transfer,　and　the　strong　connection　between　active　materials　and　Ni　foam　can　promote　better　intrinsic　kinetics.　(c)　2013　Elsevier　Ltd.　All　rights　reserved.
