【 摘 要 】

So as to change the conductivity and stationarity of NiO anode materials which was in lithium batteries, the precursors were synthesized through solvothermal measure and NiO/Ni/C composites were prepared by high temperature carbonization. The material composition was analyzed by a method named X-ray diffraction. The surface of the material was characterized through scanning electron microscopy and transmission electron microscopy, and applied to the negative electrode of lithium battery for electrochemical performance test. The results show that the NiO/Ni/C composite with pore structure has excellent performance and cycle stability in electrochemical tests. The NiO/Ni/O electrode still achieved a specific capacity of 743.7 mAh•g-1 according to cycling 100 at 0.36 A•g-1.
