英文摘要： Recently, it has been a hot research to design and develop variates of compound with different mophology to discuss the electrochemical stroage performance. Here, the fabrication of nano-composite material precuesor with arry structure is by multistep method. First, one metal oxide with array structure is fabricated by solvothermal method; then, another proper metal oxide is selected to assemble with the metal oxide precursor with array structure by ion exchange, trend to connect, self-assemble mechanism and the way of electrochemical/solvothermal/reflux. The influence of the different reaction parameters on the component, structure and performance is to be analysed. The optimized parameter and method is to be discussed. To obtain good performance of electrochemical energy storage, the nano-composite material with different array structure and nano-composite material composed of different component with same structure is controlled to fabricated. The mechanism of the electrochemical energy storage is to be discussed, special for the deep understand of the charge transport mechanism of the nano-composite interface. This research develops new way to synthetise nano-composite material, and connect the relation between internal crystal structure of nano-material with its assembleing structure, and provide experimental foundation and scientific basis for the reality of the well electrochemical energy storage performance.
