Copper oxide and ordered mesoporous carbon composite with high performance using as anode material for lithium-ion battery

A composite of leaf-shaped copper oxide (CuO) nanoparticles mainly covered on the ordered mesoporous carbon CMK-3 is synthesized by a facile precipitation method. This material (CuO/CMK-3) has been characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and nitrogen sorption. Electrochemical analyses show that the material possesses excellent cycling stability and high rate capability with an average discharge capacity of 171 mAh g−1 at 25 C using as the anode material for lithium-ion battery.
