Abstract：

In this work, three kinds of ultrathin tremella-like MnO₂ have been simply synthesized by decomposing KMnO₄ under mild hydrothermal conditions. When applied as electrode materials, they all exhibited excellent electrochemical performance. The as-prepared MnO₂ samples were characterized by means of XRD, SEM, TEM and XPS. Additionally, the relationship of the crystalline nature with the electrochemical performance was investigated. Among the three samples, the product with the poorest crystallinity had the highest capacitance of 220 F/g at a current density of 0.1 A/g. It is thought that the ultrathin MnO₂ nanostructures can serve as promising electrode materials for supercapacitors.

Key words： hydrothermal manganese dioxide supercapacitor electrochemical property
