Transition metal oxides (MO) have been widely investigated as promising anode materials for lithium-ion batteries, but suffer from the problems of irreversible capacity loss and poor cycling stability resulting from intrinsic poor conductivity, large volume expansion/contraction during the discharge/charge processes. Despite two main types of effective efforts, i.e., preparing pre-designed nano/microstructures...
A facile solvothermal technique is developed to prepare a nickel oxide precursor which is subsequently calcined in air at 300°C for 4h to convert it to NiO nanospheres. These nanospheres are assembled from ultrathin mesoporous nanosheets that possess high surface areas. The final product is characterized by various techniques: thermogravimetric analysis, X-ray diffraction, Fourier transform infrared...
