镍基活性材料用于高性能超级电容器的研究进展

Nickel based materials such as nickel hydroxide, nickel oxide and other nickel salts are widely used in various electrochemical energy storage devices due to their high theoretical capacity, good chemical and thermal stability, low price and other excellent features. This paper describes in detail about the progress of nickel-based active materials in the study of high performance supercapacitors, including its preparation process, modification methods, and performance and structure of the measured characterization.Also describes in detail about the relationship between the specific capacity of a single nickelbased active material and its preparation, microstructure, particle size, specific surface area, and porosity. As well as through the composite nickelbased materials to overcome thepoor conductivity, electron and ion channel blocked and other issues to improve the specific capacity, cycle performance and rate performance.
