摘要: Birnessite-type MnO2 (delta-MnO2) nano-sheets were successfully synthesized by an interfacial synthesis method in this work. The properties and electrochemical performance of the as-prepared delta-MnO2 analyzed evaluated scanning electron microscopy (SEM), X-ray diffraction (XRD), nitrogen adsorption measurement tests. This facile enables to show a large specific surface area (257.5 m(2) g(-1)). test results that capacitance is 272 F g(-1) retention over 96.7% after 1000 cycles at scan rate 10 mV s(-1). All demonstrate has great potential application high-performance capacitors, will be very promising synthesize highly active materials scale.
