摘要
1.Introduction Due to the excessive consumption of traditional fossil fuels and the increasing worsening of environment problem,it is imperious to develop some high-performance energy conversion and storage devices[1-4].Supercapacitors,as an efficient and green energy storage system,possess high power density and long cycle life[5].However,the poor electron conductivity and low energy density limit their wide applications.It is well known that electrochemical performance is largely affected by the structure and preparation method of the material.Therefore,it is necessary to design and develop some ideal electrode materials through effective strategies.
